Our A2 Tool Steel Blades are cryogenically treated, hardened to Rockwell 60-62 and double tempered. We use a heat treating technique that ensures the blade will take and hold a very fine edge for a long time. We have designed these blades to fit our tools, not other makers'.
After heat treating, the blade is fully surface ground on the top, back, and cutting edge, giving a smooth, flat surface that will take a mirror finish very quickly.
Our blades are thick to provide solid, chatter-free cutting. They come ready to use, but honing a secondary bevel of 5° to 10° will increase performance, help achieve a razor edge quickly, and improve edge life in hardwoods.
