a. To sharpen a blade, clamp the blade in a vise and,
using a flat mill file, carefully file the cutting surface
on each end of the blade to a sharp edge.

removed by filing should be replaced.
h. After sharpening, check the balance of the blade by
placing the blade on a blade balancer fulcrum
device.

cutting surface on that end. NOTE: If a blade
cannot be easily balanced, replace it.
