Drawknife Forged from Tool Steel, with Two Handles
A drawknife is a long blade with a handle at each end, pulled toward you to shave wood, usually with the work held in a shaving horse. Forge a blade much longer than it is deep, draw a tang at each end and bend both forward, grind one bevel of about 25°, harden and temper, and fit two wooden handles.
