CPM-3V: The Su­per Steel?

Knives Illustrated - - Personal Defense -

There seems to be a lot of de­bate and dis­cus­sion on the amaz­ing prop­er­ties of CPM-3V. Sim­ply put, as long as the heat treat is done prop­erly, you can ex­pect wear re­sis­tance about 50 per­cent bet­ter than D-2 with the abil­ity to har­den to RC 56-60, and im­pact re­sis­tance greater than A-2, D-2, Cru-wear or CPM-M4. For large chop­pers it is an amaz­ing steel due to its tough­ness, while for smaller bushcraft-style knives, it holds an amaz­ing edge—again pro­vid­ing the heat treat is on point. Also, due to its low al­loy con­tent, it is fairly easy to sharpen in a pinch. One thing im­por­tant to note how­ever, is that it is not very corrosion re­sis­tant, mean­ing that you will want to keep your blade oiled up when not in use, or you may be strop­ping off rust, or hav­ing to grind it off on your sharp­en­ing stone in more se­ri­ous cases.
