All our blades have a lapped face and are ground with a bevel that requires only final honing to 30° before use.
The O1 steel blades are hardened to Rc58-60. While O1 sharpens more easily than PM-V11, it also dulls more readily.
Our PM-V11 tool steel (Rc61-63) has a fine, consistent grain structure that provides significantly greater resistance to damage from both impact and wear than O1 steel, yet the edge can be quickly restored using water stones or other common sharpening methods.
Available in 2" and 2 3/8" widths.
