Sharpening/
Replacing Blade
The upper blade of the Model T32957 has two
cutting edges so that if one cutting edge becomes
dull, you can reverse the blade and use the fresh,
sharp cutting edge.
If both of the upper blade cutting edges are dull,
or the cutting edge of the lower blade is dull,
sharpen the blade(s) on a surface grinder and
make sure the blade is flat along the entire length.
Re-sharpen each blade edge as needed until it is
too thin to safely install (as described in the steps
below), then replace the blade. We recommend
you keep an extra set of blades on hand to avoid
any downtime.
