Tom Clarke Tactical Knives made out of 3V Steel

Tom Clarke and Duane Dwyer spent countless hours,  arriving at the material chosen for the tactical application of a knife. As with Duane’s metallurgy expertise, he suggested to use the 3V steel for the working blades. Some of the typical applications of 3V are; Punches, Dies, Shear Blades and Chopper Rolls.  If the steel is tough enough for those types of uses, TC agreed it would be great for blades.


CPM 3V is a high toughness, wear-resistant tool steel made by the Crucible Particle Metallurgy process. It is designed to provide maximum resistance to breakage and chipping in a high wear-resistance steel. It offers impact resistance greater than A2, D2, Cru-Wear, or CPM M4, approaching the levels provided by S7 and other shock resistant grades. CPM 3V is intended to be used at 58/60 HRC in applications where chronic breakage and chipping are encountered in other tool steels, but where the wear properties of a high alloy steel are required. copyImpact Toughness 
CPM 3V offers impact toughness approaching the shock-resistant tool steels, with much greater wear resistance. Resistance 
CPM 3V offers substantial improvements in tool wear life when compared with conventional tool steels such as A2 and D2. CPM 3V’s high vanadium content offers wear resistance similar to M2 high speed steel.
