Putty Knife

The Putty Knife's edge is shaped on a belt sander (preferred) or bench grinder.

The leading edge is ground to be straight across, and 90° to the edges. There is no thinning of the leading edge to form a blade (as with a scraper).

Notes & Comments

Information regarding Grindstones

If grinding this on a high speed grinder, be sure to manage the temperature so that the temper is not lost due to overheating. If there is a carbide insert, DO NOT cool by dipping in water. This will cause the carbide to crack due to shocks. Otherwise, cool by dipping as needed in water.
