CPM-3V: The Super Steel?
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.
