W ear pr oper ey e pr otection when shar pening
blade.
1. Use a file to shar pen the cutting edg e at both
ends of the blade ( Figure 66 ). Maintain the
original angle . T he blade retains its balance if
the same amount of material is remo v ed from
both cutting edg es .
Figure 66
1. Sharpen at original angle
2. Chec k the balance of the blade b y putting it on
a blade balancer ( Figure 67 ). 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 68 ). R e peat this procedure until the
blade is balanced.
