250x53 CPM-154 Gyuto
This is the first knife that I’ve produced in stainless that is not Damasteel. The steel used for this knife is CPM-154. I have done quite a bit of testing on the steel and have heat treated it to 61-62 HRC. CPM-154 is a fine grained powdered steel. This steel is manufactured by Crucible Industries and all of their products are made in USA. The handle of this knife is composed of curly Tasmanian Blackwood with an African Blackwood ferrule. The spacer is red dyed mammoth tooth.
This knife has a compound S-grind, which is a hollow along the middle of the blade which aids with food release. Previously, I used a platen that replicated the angle of a 48” wheel for this. As of lately, I have started using a platen that replicates a 36” wheel, I find the slightly deeper hollow creates a more acute apex.
