Using Stamps - Identify Almost Anything!
Draw guidelines on the item to be marked. NOTE: on tools, avoid hardened or tempered surfaces. Position item on a flat, solid surface.
Align groove with thumb, firmly grasp the stamp halfway down the shank.
Position the stamp between the guidelines. Rest hand firmly on the item to be marked.
With a moderate but solid blow of a hammer, the item is marked!
