All of our blades are put through a 12 step process to guaranteeing quality and craftsmanship.We start with a fine-grain carbon steel that is heat treated to create a hard surface for greater wear resistance. Our patented Cryogen-X process takes the blades down to a -300 degrees for a deep freeze, producing a harder, sharper blade which extends the product life. Each blade is then hand lapped for a smooth cut finish. Our Elite Blade Collection features an expertly applied finish on high carbon steel to ensure maximum blade performance and lasting sharpness, leveraging a Rockwell Hardness Rating of 64.
