If an electric grinder is used, use care not to overheat teeth, do not
allow tips/tooth to glow red or turn blue. DO NOT place blade in
cooling water. This will change the temper of the blade and could
result in blade failure.

After sharpening teeth, check
each tooth radius for evidence
of a square (sharp) corner. Use
the round (rat tail) file to renew
the radius.
