Cold Steel Recon Tanto in SK-5

The Cold Steel Recon Tanto was designed for today's modern warriors. A much loved and appreciated knife by the Military and Law Enforcement Special Units, it was developed to withstand the harshest abuse and the toughest possible conditions. The signature Cold Steel Tanto point is specially reinforced to stay sharp even when encountering modern body armor - tested right in their HQ by punching through 55-gallon steel drums! This classic design is now available with SK-5 high carbon steel. It is the Japanese equivalent of American 1080, a high carbon steel with carbon between 0.75%-0.85% and 0.60%-0.90% manganese. As quenched, it has a hardness near Rc 65 and produces a mixture of carbon rich martensite with some small undissolved carbides. The excess carbide increases abrasion resistance and allows the steel to achieve an ideal balance of very good blade toughness with superior edge holding ability.
