220mm CPM-154CM Gyuto Chef Knife

A 220mm CPM-154 gyuto

CPM154 is the powder metallurgy version of the classic 154-CM used widely in knives for decades. A modified version of the grand-daddy of all stainless cutlery steels (440C) it has  higher edge retention, higher attainable hardness, and significantly improved corrosion resistance than 440c, and the powder metallurgy version has double the toughness of its ingot cast counterpart. If you like PM steels but were looking for something easier to sharpen than MagnaCut or M4 that’s also fully stainless, this 220mm CPM-154 Gyuto could be for you!
