Sharpening the Blade
Using a file, sharpen top side of the blade and maintain
the original cutting angle (Fig. 23).
1. Sharpen at this angle only
Note: The blade will remain balanced if same amount of
material is removed from both cutting edges.
Balancing the Blade
1. Check the balance of the blade by placing the center
hole of the blade over a nail or screwdriver shank
clamped horizontally in a vise (Fig. 24).
Note: You can also check the balance using a
commercially manufactured, blade balancer.
2. If either end of the blade rotates downward, file that
end (not the cutting edge or the end near the cutting
edge). The blade is properly balanced when neither
end drops.
