Sharpening the Blades
WARNING
When sharpening blade, pieces of blade could be
thrown and cause serious injury.
Wear proper eye protection when sharpening blade.
1. Use a file to sharpen the cutting edge at both ends of
the blade (Figure 77). 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 (Figure 78). 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 end of
the sail area only (Figure 79). Repeat this procedure
until the blade is balanced.
