Working with this steel

These billets are supplied hardened and are intended for stock removal rather than forging. Keep the steel cool during grinding to preserve the existing heat treatment.

Grind evenly on both sides and ensure the cutting core is exposed along the entire edge. Drilling hardened steel can be difficult and requires suitable tooling.

The final pattern and copper line will vary with the blade profile, grinding depth and finishing process.
