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