The Montana Knife Company™ Blackfoot Blade 2.0s are made from 52100 high carbon ball-bearing steel. The cryogenically heat-treated blades provide a perfect balance of toughness and edge retention. Once the razor edge has been lost it can be easily sharpened with a small stone. Unlike other knives, the Blackfoot’s edge can be maintained by even novice knife owners. Additionally, the blades have been parkerized to a black finish which will help minimize rust and glare. After use, clean the blade and occasionally apply a little wax or oil.
