CPM-3V and CPM-S35VN added into our stock range! 30 October 2017 David We are please to add another two fantastic steels from Crucible Industries into our stock range for knife making steels. Both are manufactured using the Crucible Industries powder metallurgy process giving very pure, refined steels. CPM-3V is a carbon steel that is super tough and has excellent edge holding. It is one of the toughest tool steels around out performing like S7 as a shock resistant steel while providing maximum resistance to breakage and chipping on the edge. CPM-S35VN is an evolution of S30V with added Niobium to increase resistance to edge chipping and wear resistance. It is also easier to polish and machine than S30V. This is a high end stainless knife steel for high end cutlery!
