Putty Knife
The Putty Knife's cutting edge is shaped on a 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
  • 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.

  • A great general reference is the U.S. War Department's TM 9-867 Maintenance and Care of Hand Tools.
