Sharpening the Blades

1. Sharpen at original angle
2. Chec k the balance of the blade b y putting it on
a blade balancer ( Figure 71 ). If the blade sta ys
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 69 ). R e peat this procedure until the
blade is balanced.
