CPM-Magnacut: Developed by metallurgist Larrin Thomas of Knife Steel Nerds, Magnacut is designed to deliver balanced high-performance with high hardness (up to 65 Rc), similar toughness to CPM-4V, and corrosion resistance better than M390, similar to LC200N. Sharpening is relatively easy between CPM-154 and S35VN/S45VN. Magnacut is an excellent all-purpose steel.
