the same amount of material is remo v ed from
both cutting edg es .

1. Sharpen at original angle
2. Chec k the balance of the blade b y putting it on
a blade balancer ( Figure 57 ). 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
