Sharpening the Blade

1. Use a file to sharpen the cutting edge at both ends of
the blade (Figure 40).
Note: Maintain the original angle.
Note: The blade retains balance if the same amount
of material is removed from both cutting edges.

2. For straight blades only, check the balance of the blade
by putting it on a blade balancer
If the blade is not balanced, file some metal off the
back side of the blade (opposite of the cutting edge)
only (Figure 38).
Repeat this procedure until the blade is balanced.
Note: If the blade stays in a horizontal position, the
blade is balanced.
