Paradigm Copper Diamondback (USA)



I’ve always been at the right place at the right time when it comes to finding the release of Paradigm razors. I seem to stumble onto them by accident and that is exactly how I discovered the Copper Diamondback. Someone had a Ti Diamondback for sale on Ebay at what I thought was an exorbitant price; I’ll check, no Ti listed but there is a Copper version, thank you, I’ll have one of them. I don’t have any copper razors but had been thinking of adding a copper razor to the collection for some time and a Paradigm will fit the bill nicely. Paradigm made it known in their advertisement that the copper Diamondback is a limited edition and that no sealant was used to protect the finish, therefore the razor would patina over time. As I was unpacking the Copper Diamondback I treated each part with Renaissance Wax, hopefully I will now have a sparkling Copper Diamondback for years to come, that rich beauty deserves to be maintained.

These are no visual changes to the copper Diamondback from previous releases of that model. Its distinctive look comes from the hexagonal handle with engraved diamonds strung out along each flat. Thread engagement is as good as you are ever going to get with any razor, a real credit to whoever machined it. There is nothing special about the cap with its radiused top and elongated blade posts on the underside that mate into blind holes in the top of the plate. Two wide blade clamping surfaces that mate with corresponding flats on the plate ensure that when tightened down, that blade is held firm. This lightweight head means only one thing, the handle contributes the majority of the weight of the razor, the copper Diamondback’s weight is well over magical 100g. Paradigm have done a creditable job with the polished finish; it is obviously machined, and the underside of the cap retains its machine marks.

Efficiency was on the high side of Karve CB Level #C and there was just the right amount of positive blade to meet my requirement for the near perfect shave. This efficiency level is higher than I recorded with the stainless steel version, you won’t hear me complain. As with other razors sharing these credentials, the shave was comfortable and certainly smooth. Being handle heavy was a minor impediment, a hole up the end of the handle would have worked wonders for weight reduction and balance of the razor. For such a visually spectacular razor that operates as perfectly as it does, the Paradigm Diamondback has at least one dedicated devotee. It was a little sad when I gave the Copper Diamondback another coat of Renaissance Wax to pack it away.

Lovely detailed review Errol. I've always admired Andrew's willingness to experiment, explore and change things up every now and then.

I remember shaving with the SS version released through West Coast Shaving ( 2019) and it was just okay, a year later and the new version was like a massive upgrade. Throw in the different Ti versions, the copper DB and the Salient , what a joy. Each of the Paradigm razors has a character and identity of its own.

When Paradigm release a stainless steel version again, I'm getting one into my bloody den, unless I can buy one off you @Errol

They pop up on BST very often, across many forums mate.

(Wolfman) Guerrilla Ti 0.69mm OC (Canada)



There have been many less than flattering comments about the handle of the original Guerrilla over the last eight years of manufacture regarding its lack of grip and the aesthetics of having a straight shaft with no machining other than three narrow grooves at each end. Personally, I thought the handle suited the intended purpose, I have never had a grip issue and quite liked its presentation but that did not stop me from ordering this razor with the alternate Rebel handle. With a titanium Guerrilla on offer, its selection was never in doubt, in fact this razor would never have materialized had it not been titanium. Having previously been blown away by the performance of the 0.69mm plate, selection for the blade gap was simple; might as well try an open comb though. Also offered was a second plate so I grabbed a 0.84mm SB plate and that will be the review for next week. All the usual Guerrilla features are present including no excess material in the cap or the plate, blade clamping at the very edge, round blade posts on the cap that mate into blind holes in the plate, Guerrilla’s ever commendable thread engagement and the standard satin finish. Another feature I’d like to commend Guerrilla on is that each plate now has the blade gap engraved at the rear.

First shave completed and I’m caught off guard, so I scuttle out for my glasses to check that the plate really does have 0.69 engraved on it and my records of the SB 0.69; the Ti’s aggression was far more than I was expecting. Efficiency for the 0.69 plated OC Guerrilla was in excess of Karve CB Level #D and it had blade feel by the truck load; back to the old days of the OC version of a razor being more aggressive that the SB plated version. My approach to subsequent shaves was a lot more cautious. A close shave was never in doubt and some weepers on can testify to that; nothing major, just those small patches that close almost immediately. The teeth on the comb can be felt but they are rounded and smooth, so they just glide over the face and become a non-event after the first couple of shaves. Lately I’ve become critical of razor balance, especially on titanium razors, so it is pleasing to report that the Guerrilla’s balance is very good. It displays all the qualities of a top shelf razor, I have been a fan of the Guerrilla since its first inception and now with the blade posts relocated to the cap, a choice of efficiency levels and four different metals to choose from, I can’t speak highly enough of the Guerrilla. I appreciated my time with the 0.69mm OC plated Guerrilla but it demands respect.

That is a whole lot of blade sticking out beyond the cap there @Errol, looking forward to seeing if your .84 SB turns out to be a monster...

(Wolfman) Guerrilla Ti 0.84mm (Canada)



This week’s review is again with the Guerrilla Ti razor but fitted with the more efficient 0.84mm safety bar plate. Just what I don’t want, more blade gap than the 0.69mm plate used last week, I was not expecting that outcome. The satin finish that is a feature of every Guerrilla razor does a remarkable job in providing grip, it also helps when I favour a satin finish over just about every other finish available. Most machine finishes leave the razor with sharp edges and looking half done, polished surfaces must be done properly and look dejected as soon as the inevitable fingerprint appears; just give me a hard working satin finish any day. While it is nothing in the scheme of things, the Guerrilla fitted with the safety bar plate was 0.5g lighter than the corresponding open comb. Blade clamping at the outer edge of the cap, round blade posts fitted into blind plate holes and one long lather clearing channel are all features of this Guerrilla.

With efficiency just over Karve CB Level #D and a substantial, but not overpowering amount of positive blade, the 0.84mm plated Ti Guerrilla performed exactly as I was expecting. This razor could not be described as overly smooth, but it was certainly comfortable. There was never any concern for my safety but if your technique is not quite up to scratch, I’d suggest proceeding with extreme caution. Combined with its bead blasted finish, the circular grooves around the grip area provided the alternate Rebel handle with positive grip. Personally, I wouldn’t say the Rebel handle is better than the Original Guerrilla handle, but it is different. My time with the Guerrilla left me with many unanswered about the OC plate I used last week, but I was in awe of the performance of the Guerrilla Ti 0.84mm SB.

Alpha Spirit SE Bronze (Hong Kong)



Fancy Alpha Shaving putting out a bronze version of their Spirit SE and me not buying one. Fat chance of that when I’m a sucker for bronze razors and I really appreciated my time with their stainless steel Spirit SE. Other than being machined from bronze, the Spirit looks identical to the Stainless Steel version. There is no machined down handle post to slip through the elongated hole in the AC blade; the handle post is positioned above the blade but because every part of the razor has been machined to very fine tolerances, the razor manages to look small; the thin handle with its long neck also plays a large part in making the razor appear small. Alpha have also drilled out the end of the handle to effectively reduce its weight further; they done this with the stainless steel variant so nothing new there.

First shave, ‘What the?’ Nothing! it was just like there was no blade in the razor. Strip the razor down, the Feather Professional is in correctly, reassemble and everything looks correct. Still nothing. Race out and grab another blade from the first canister I find; it just happens to be The Speed Master’s least favoured blade, the Feather ProGuard. At least it worked. That’s something that’s not happened to me before, that’s life so get on with it. I refrained from making any judgement on the Spirit SE Bronze at this time. Subsequent shaves and I’m back to normal and can start making judgement; just what I was expecting, Karve CB Level #D efficiency and a pleasant amount of positive blade. Everything about this razor impresses, it is light weight, comfortable and silky smooth. Where the bronze version outshines the stainless steel version is in the looks department especially before the inevitable tarnish commences, that golden sparkle is mesmerizing. I applied Renaissance Wax so that will slow down the onslaught of tarnish and I did remember to apply another cote of wax before it was stored away. It is certainly one of the better razors available on the market today.

Great review, I throughly enjoy mine above the Blackland & Shield (IMHO) and find/believe that Bronze gives a “smoother” shave over the same amount of S/S on any given part of your face?

I did a metal comparison on Badger and Blade - The test subject: the Alpha Spirit Artist Club razor, a precision-crafted AC-style razor available in four metals: Stainless Steel, Copper, Bronze, and Titanium. All four razors feature identical geometry, blade exposure, and design—making them perfect candidates for a true material showdown.

Ran it as an elimination challenge.
Initiall, each razor was loaded with the same Feather Pro AC blade—no switching things up mid-test. For consistency,I used the always-reliable Arko shaving soap to eliminate variables in cushion, slickness, and lather performance and a Kirin knot Oumo brush. This is about one thing: how the metal alone changes the shave.

In the process, I introduced the Kai Pink Mild AC blade and the Feather Super

From the posts

What to Expect (Based on Physics):​

Before we start, here’s a little preview of what science might suggest:
Stainless Steel – Dense and relatively heavy, stainless tends to offer great stability and momentum. Expect a smooth, confident shave with moderate feedback and low chatter. A good baseline.
Copper – Softer and denser than stainless. Often offers a slightly "smoother" face feel due to its damping characteristics, but its weight may amplify blade feel. Could shine in efficiency but punish poor technique.
Bronze – Similar density to copper but a bit harder. Usually feels refined and warm on the skin. Could strike the best balance between smoothness and authority. We’ll see.
Titanium – The wild card. Lightweight yet strong, titanium razors often feel more nimble and require a lighter touch. Expect more audible feedback, more maneuverability—but perhaps more blade feel or "bite" if your pressure is off.

What I was looking at:

• Blade feel
• Smoothness
• Maneuverability
• Post-shave comfort (including alum feedback)
• Closeness
• Fun factor

Here is the final post (it went on for two weeks - reported like an Olympic Boxing Competition if you want a fun read here is the entire series:

Final Report: Alpha Spirit Metal Meltdown​

Champion: Alpha Spirit Titanium — “One Razor to Rule Them All”
The Alpha Spirit Metal Meltdown set out to crown the best razor-metal combination across Stainless, Copper, Bronze, and Titanium using two premium Artist Club blades — the Feather Professional and the Kai Titan Mild PINK. The results were clear: while the Titanium Spirit stood tall in both competitions, the real revelation came with the performance of the Kai blade.

Why Did the Kai Titan Mild PINK Do So Well?​

To understand this, we must break down what contributes to a razor's efficiency and aggressiveness:

• Blade Sharpness: A sharper blade cuts cleaner and faster.
• Blade Exposure: The more a blade extends beyond the razor head, the more aggressive the shave.
• Razor Geometry: Blade gap, angle, and clamping influence how efficiently the razor delivers a shave.
• Shaving Technique: In our tests, this variable was controlled — so differences stemmed from the blades and razors alone.

Blade Geometry Comparison​

Feather Professional

• Thickness: 0.254 mm
• Width: 8.0 mm

Feather Professional SUPER

• Thickness: 0.310 mm
• Width: 8.2 mm
• Coating: Dual-layer (Platinum alloy + resin for smoothness)

Kai Titan Mild PINK

• Thickness: 0.320 mm
• Width: 8.2 mm
• Coating: Plasma Ion New (PINK) tech — titanium coating for durability, PTFE for smoothness

The Kai’s geometry closely mirrors the Feather SUPER, but it consistently delivered smoother, more comfortable shaves — with no loss of efficiency.

Titanium vs the Field: Kai Edition​

In direct comparison:

• • The Titanium razor paired with the Kai blade removed more stubble in fewer passes than with the Feather Pro, and nearly matched the sheer cutting power of the Feather SUPER — without provoking the wrath of the Alum.
  • The Copper razor, though gorgeous and smooth with the Kai, could not match Titanium’s maneuverability or post-shave results. It also requires more maintenance due to patina formation.
  • The Feather SUPER, while highly effective in terms of raw cutting power, drew blood when paired with the more aggressive heavier metals like Copper — proving that sharpness alone isn't always superior.

Conclusion: The Kai Advantage​

Despite similar dimensions to the Feather SUPER, the Kai Titan Mild PINK distinguishes itself with cutting-edge metallurgy. The PINK process — involving ion plasma hardening, titanium coating, and a PTFE finish — delivers:

• Greater durability
• Smoother glide
• Superior comfort
• Equal or better efficiency

In the Alpha Spirit lineup, this meant every razor performed better with the Kai blade, but especially Titanium — which took the crown with grace, comfort, and a flawless post-shave feel.

Final Judgement​

In both the Feather and Kai competitions, Titanium Spirit stood alone as the undisputed champion. When paired with the Kai Titan Mild PINK, it achieved a level of balance between sharpness, comfort, efficiency, and elegance that no other combination could match.
If I had to keep only one Spirit, it would be the Titanium - a razor for all seasons and fun to drive. A great everyday razor when paired with the KAI or FEATHER. But like a moth to a flame - Copper and Bronze will stay for when a little "Sensory Richness" or "Experiential Depth" is desired. As I said before, the Universe is fair, but the added care and maintenance is worth it, once in a while.
I will also keep the Stainless - a workhorse. Perhaps as the travel razor to alternate with Blackland Workshop 002.

Well done, that's a great synopsis of your conclusions. As a matter of interest, since I remember you have a WR4, I confess to a certain curiosity as to whether or not you have any preference between the two. (Hmmm, I think you mentioned you have La Faulx too - such riches... )

As far as blades are concerned, I more or less settled that for myself when I first got my Vector. BTW, I can't make any more rigorous a claim than to say it's my impression that blade:skin is a more useful comparison than blade:razor. It's a shame that that excludes a rigorous scientific comparison, but that's just too bad, sometimes life is like that.

I spent several months comparing Feather Pro, Feather Pro Super, Kai Captain Titan Mild (PINK), Schick Proline (P30), and much more recently, Proshave S. Eventually I decided the Schick blades worked best for me, and ended up buying 600 of them, so they'll probably last me out. Since then, I've never looked at anything else. But I believe the Kai PINK to be a very creditable second.

BTW, I can't make any more rigorous a claim than to say it's my impression that blade:skin is a more useful comparison than blade:razor. It's a shame that that excludes a rigorous scientific comparison, but that's just too bad, sometimes life is like that.

I spent several months comparing Feather Pro, Feather Pro Super, Kai Captain Titan Mild (PINK), Schick Proline (P30), and much more recently, Proshave S. Eventually I decided the Schick blades worked best for me, and ended up buying 600 of them, so they'll probably last me out. Since then, I've never looked at anything else. But I believe the Kai PINK to be a very creditable second.

It's funny, i sometimes feel like I am trying to figure out how many angels can fit on the head of a pin with some of my research. 90% of the time you can compensate for blade or razor with familiarity and technique... but there be dragons in that other 10%.

For any AC blade I prefer the LA Faulx. Price performance it is really hard to beat the Spirit. The WR4 is great and I don't plan on getting rid of it, but not sure I'd buy it for me (YMMV) having the AD.

(Wolfman) Guerrilla Ti 0.69mm OC (Canada)



There have been many less than flattering comments about the handle of the original Guerrilla over the last eight years of manufacture regarding its lack of grip and the aesthetics of having a straight shaft with no machining other than three narrow grooves at each end. Personally, I thought the handle suited the intended purpose, I have never had a grip issue and quite liked its presentation but that did not stop me from ordering this razor with the alternate Rebel handle. With a titanium Guerrilla on offer, its selection was never in doubt, in fact this razor would never have materialized had it not been titanium. Having previously been blown away by the performance of the 0.69mm plate, selection for the blade gap was simple; might as well try an open comb though. Also offered was a second plate so I grabbed a 0.84mm SB plate and that will be the review for next week. All the usual Guerrilla features are present including no excess material in the cap or the plate, blade clamping at the very edge, round blade posts on the cap that mate into blind holes in the plate, Guerrilla’s ever commendable thread engagement and the standard satin finish. Another feature I’d like to commend Guerrilla on is that each plate now has the blade gap engraved at the rear.

First shave completed and I’m caught off guard, so I scuttle out for my glasses to check that the plate really does have 0.69 engraved on it and my records of the SB 0.69; the Ti’s aggression was far more than I was expecting. Efficiency for the 0.69 plated OC Guerrilla was in excess of Karve CB Level #D and it had blade feel by the truck load; back to the old days of the OC version of a razor being more aggressive that the SB plated version. My approach to subsequent shaves was a lot more cautious. A close shave was never in doubt and some weepers on can testify to that; nothing major, just those small patches that close almost immediately. The teeth on the comb can be felt but they are rounded and smooth, so they just glide over the face and become a non-event after the first couple of shaves. Lately I’ve become critical of razor balance, especially on titanium razors, so it is pleasing to report that the Guerrilla’s balance is very good. It displays all the qualities of a top shelf razor, I have been a fan of the Guerrilla since its first inception and now with the blade posts relocated to the cap, a choice of efficiency levels and four different metals to choose from, I can’t speak highly enough of the Guerrilla. I appreciated my time with the 0.69mm OC plated Guerrilla but it demands respect.

Excellent review @Errol and an eye opener of why blade gap isn't an indicator or aggression or efficiency.

(Wolfman) Guerrilla Ti 0.84mm (Canada)



This week’s review is again with the Guerrilla Ti razor but fitted with the more efficient 0.84mm safety bar plate. Just what I don’t want, more blade gap than the 0.69mm plate used last week, I was not expecting that outcome. The satin finish that is a feature of every Guerrilla razor does a remarkable job in providing grip, it also helps when I favour a satin finish over just about every other finish available. Most machine finishes leave the razor with sharp edges and looking half done, polished surfaces must be done properly and look dejected as soon as the inevitable fingerprint appears; just give me a hard working satin finish any day. While it is nothing in the scheme of things, the Guerrilla fitted with the safety bar plate was 0.5g lighter than the corresponding open comb. Blade clamping at the outer edge of the cap, round blade posts fitted into blind plate holes and one long lather clearing channel are all features of this Guerrilla.

With efficiency just over Karve CB Level #D and a substantial, but not overpowering amount of positive blade, the 0.84mm plated Ti Guerrilla performed exactly as I was expecting. This razor could not be described as overly smooth, but it was certainly comfortable. There was never any concern for my safety but if your technique is not quite up to scratch, I’d suggest proceeding with extreme caution. Combined with its bead blasted finish, the circular grooves around the grip area provided the alternate Rebel handle with positive grip. Personally, I wouldn’t say the Rebel handle is better than the Original Guerrilla handle, but it is different. My time with the Guerrilla left me with many unanswered about the OC plate I used last week, but I was in awe of the performance of the Guerrilla Ti 0.84mm SB.

Alpha Spirit SE Bronze (Hong Kong)



Fancy Alpha Shaving putting out a bronze version of their Spirit SE and me not buying one. Fat chance of that when I’m a sucker for bronze razors and I really appreciated my time with their stainless steel Spirit SE. Other than being machined from bronze, the Spirit looks identical to the Stainless Steel version. There is no machined down handle post to slip through the elongated hole in the AC blade; the handle post is positioned above the blade but because every part of the razor has been machined to very fine tolerances, the razor manages to look small; the thin handle with its long neck also plays a large part in making the razor appear small. Alpha have also drilled out the end of the handle to effectively reduce its weight further; they done this with the stainless steel variant so nothing new there.

First shave, ‘What the?’ Nothing! it was just like there was no blade in the razor. Strip the razor down, the Feather Professional is in correctly, reassemble and everything looks correct. Still nothing. Race out and grab another blade from the first canister I find; it just happens to be The Speed Master’s least favoured blade, the Feather ProGuard. At least it worked. That’s something that’s not happened to me before, that’s life so get on with it. I refrained from making any judgement on the Spirit SE Bronze at this time. Subsequent shaves and I’m back to normal and can start making judgement; just what I was expecting, Karve CB Level #D efficiency and a pleasant amount of positive blade. Everything about this razor impresses, it is light weight, comfortable and silky smooth. Where the bronze version outshines the stainless steel version is in the looks department especially before the inevitable tarnish commences, that golden sparkle is mesmerizing. I applied Renaissance Wax so that will slow down the onslaught of tarnish and I did remember to apply another cote of wax before it was stored away. It is certainly one of the better razors available on the market today.

I did a metal comparison on Badger and Blade - The test subject: the Alpha Spirit Artist Club razor, a precision-crafted AC-style razor available in four metals: Stainless Steel, Copper, Bronze, and Titanium. All four razors feature identical geometry, blade exposure, and design—making them perfect candidates for a true material showdown.

Ran it as an elimination challenge.
Initiall, each razor was loaded with the same Feather Pro AC blade—no switching things up mid-test. For consistency,I used the always-reliable Arko shaving soap to eliminate variables in cushion, slickness, and lather performance and a Kirin knot Oumo brush. This is about one thing: how the metal alone changes the shave.

In the process, I introduced the Kai Pink Mild AC blade and the Feather Super

From the posts

What to Expect (Based on Physics):​

Before we start, here’s a little preview of what science might suggest:
Stainless Steel – Dense and relatively heavy, stainless tends to offer great stability and momentum. Expect a smooth, confident shave with moderate feedback and low chatter. A good baseline.
Copper – Softer and denser than stainless. Often offers a slightly "smoother" face feel due to its damping characteristics, but its weight may amplify blade feel. Could shine in efficiency but punish poor technique.
Bronze – Similar density to copper but a bit harder. Usually feels refined and warm on the skin. Could strike the best balance between smoothness and authority. We’ll see.
Titanium – The wild card. Lightweight yet strong, titanium razors often feel more nimble and require a lighter touch. Expect more audible feedback, more maneuverability—but perhaps more blade feel or "bite" if your pressure is off.

What I was looking at:

• Blade feel
• Smoothness
• Maneuverability
• Post-shave comfort (including alum feedback)
• Closeness
• Fun factor

Here is the final post (it went on for two weeks - reported like an Olympic Boxing Competition if you want a fun read here is the entire series:
https://www.badgerandblade.com/foru...irit-does-the-metal-make-a-difference.668316/ )

Final Report: Alpha Spirit Metal Meltdown​

Champion: Alpha Spirit Titanium — “One Razor to Rule Them All”
The Alpha Spirit Metal Meltdown set out to crown the best razor-metal combination across Stainless, Copper, Bronze, and Titanium using two premium Artist Club blades — the Feather Professional and the Kai Titan Mild PINK. The results were clear: while the Titanium Spirit stood tall in both competitions, the real revelation came with the performance of the Kai blade.

Why Did the Kai Titan Mild PINK Do So Well?​

To understand this, we must break down what contributes to a razor's efficiency and aggressiveness:

• Blade Sharpness: A sharper blade cuts cleaner and faster.
• Blade Exposure: The more a blade extends beyond the razor head, the more aggressive the shave.
• Razor Geometry: Blade gap, angle, and clamping influence how efficiently the razor delivers a shave.
• Shaving Technique: In our tests, this variable was controlled — so differences stemmed from the blades and razors alone.

Blade Geometry Comparison​

Feather Professional

• Thickness: 0.254 mm
• Width: 8.0 mm

Feather Professional SUPER

• Thickness: 0.310 mm
• Width: 8.2 mm
• Coating: Dual-layer (Platinum alloy + resin for smoothness)

Kai Titan Mild PINK

• Thickness: 0.320 mm
• Width: 8.2 mm
• Coating: Plasma Ion New (PINK) tech — titanium coating for durability, PTFE for smoothness

The Kai’s geometry closely mirrors the Feather SUPER, but it consistently delivered smoother, more comfortable shaves — with no loss of efficiency.

Titanium vs the Field: Kai Edition​

In direct comparison:

• • The Titanium razor paired with the Kai blade removed more stubble in fewer passes than with the Feather Pro, and nearly matched the sheer cutting power of the Feather SUPER — without provoking the wrath of the Alum.
  • The Copper razor, though gorgeous and smooth with the Kai, could not match Titanium’s maneuverability or post-shave results. It also requires more maintenance due to patina formation.
  • The Feather SUPER, while highly effective in terms of raw cutting power, drew blood when paired with the more aggressive heavier metals like Copper — proving that sharpness alone isn't always superior.

Conclusion: The Kai Advantage​

Despite similar dimensions to the Feather SUPER, the Kai Titan Mild PINK distinguishes itself with cutting-edge metallurgy. The PINK process — involving ion plasma hardening, titanium coating, and a PTFE finish — delivers:

• Greater durability
• Smoother glide
• Superior comfort
• Equal or better efficiency

In the Alpha Spirit lineup, this meant every razor performed better with the Kai blade, but especially Titanium — which took the crown with grace, comfort, and a flawless post-shave feel.

Final Judgement​

In both the Feather and Kai competitions, Titanium Spirit stood alone as the undisputed champion. When paired with the Kai Titan Mild PINK, it achieved a level of balance between sharpness, comfort, efficiency, and elegance that no other combination could match.
If I had to keep only one Spirit, it would be the Titanium - a razor for all seasons and fun to drive. A great everyday razor when paired with the KAI or FEATHER. But like a moth to a flame - Copper and Bronze will stay for when a little "Sensory Richness" or "Experiential Depth" is desired. As I said before, the Universe is fair, but the added care and maintenance is worth it, once in a while.
I will also keep the Stainless - a workhorse. Perhaps as the travel razor to alternate with Blackland Workshop 002.

Superb breakdown and feedback on the different metals of the Alpha Spirit. I know that the Spirit is also Steve's favorite razor and he would love to read this.

Top stuff @stikeyoda

Alpha Spirit SE Titanium (Hong Kong)



Lately I’m becoming a little concerned that the heads on many quality titanium razors have had all the excess material removed and have become very light, they require more weight or a lighter handle to balance the razor. I wasn’t going to review this razor initially but after thinking about it for a while, this razor is a prime candidate that could well fall into the category of the head being too light. Somehow, I have a feeling that with its long, slim and elegant handle, the Spirit SE Titanium may just be OK, I’m about to put it to the test. Everything that’s been written about other versions of the Alpha Spirit SE relates to their Titanium version; it really is an impressive looking razor. As for the weight of the razor, it is extremely light, requiring almost three complete razors to exceed the ‘magical’ 100g mark. Finished in what I suspect to be a very high quality machine finish, this razor really has a presence; while it is small in stature it visibly stands out.

As expected, there was no cause for concern as to the balance of the razor, the pencil thin handle with its drilled out end and pared down neck ensured that the balance was spot on. Karve CB Level #D efficiency and the same pleasurable amount of positive blades as its stable mates ensured a smooth and comfortable shave. Alpha’s Sprint SE Ti is a pleasure to use, and I’d go so far as to say it my choice of razors in the Sprint range, I’m pleased I didn’t bypass it now.

Blackland Sabre II Ti - #3 (USA)



Blackland’s email advising that their Sabre II was to be discontinued took me by surprise. The November Black Friday sales were still a way off and I’d been holding out to get one at a discounted price, caught out by my own frugality. By that time there would be none available, only one thing to do, lay down my hard earned and get one before they disappeared. Stainless steel? Titanium? both versions were available but being a titanium devotee, the selection of material was straight forward. I’ve been caught out previously by the less than desirable machined finishes on Blackland products, so the polished version was selected. What a stunning polished finish Blackland has presented on the Sabre II, every side of each piece has been meticulously done. Well, that is not quite true; the forward grip on the handle retains a machined finish, providing both contrast and positive grip. Highlighting the whole Sabre II package is that efficiency can be swapped by flipping over a removable safety bar section at the leading edge of the plate. Two bar sections are provided, thus giving the purchaser four different efficiency levels to choose from. For this review I have selected the #3 bar section, so I’ll see how that goes before trying to determine my next level to try or even if I need another selection. Taking its que from the original Sabre, the sides of the handle post have been machined off to permit it to protrude through the hole in the centre of the GEM blade to give the Sabre II a small head profile. With the desired bar section and blade fitted, the head is clamped down in a flat package.

My selection of the #3 bar section was based on personal preference for efficiency just above mid-range, the #3 bar section fitted that criteria in theory. However, it did not take long to discover that I had chosen too high an efficiency level with the #3 bar section; efficiency was slightly on the high side Karve CB level #D which was not a problem in itself, but the abundance of positive blade feel was less than welcome. Naturally sharp GEM blades do a fantastic job of mowing down stubble but the Sabre II with its #3 bar section fitted was leaving behind patches of weepers. Less downward pressure reduced the number of weepers but that required concentration all the way, not my idea of a comfortable shave. Of course, the shave was close, but I have had many better shaves, time to go down a notch and give the #2 bar section a whirl; with the Sabre II already out of its packaging - next week.
