Sharpening the Blades
1. Use a file to sharpen the cutting edge at both ends of the
blade (Fig. 26). Maintain the original angle. The blade
retains its balance if the same amount of material is
removed from both cutting edges.

2. Check the balance of the blade by putting it on a blade
balancer (Fig. 27). If the blade stays in a horizontal
position, the blade is balanced and can be used. If the
blade is not balanced, file some metal off the back side
of the blade. Repeat this procedure until the blade is
balanced.
