Langer PDT starts with the highest quality 440A stainless steel and then puts it through a unique process of heat treat and cryogenics. Our secret formula produces a molecular grain structure in the steel that results in optimal hardness without sacrificing strength. This process allows for thinner blades while maintaining the greatest durability. PDTs hard steel resists wear and retains the sharpest of edges much longer than ordinary steel. - Highest quality 440A stainless steel - Unique heat treat and cryogenic formula - Sharper, harder, tougher blades - Outlasts all others
