Man, I am an idiot.
I knew I had better implements to use, better knives even, but I decided to use my carbo next knife in a way it totally want designed to be used and managed to snap the end 4mm off.
To say I am pissed of with myself is an understatement.
Still I guess it gives me the chance to buy a new knife
Just grind a new point on it. You'll have a carbonext knife that's 4mm shorter and depending on the shape, maybe a bit stubbier. I've done that to a couple of knives. It's really no biggie at all.
