Follow the original angle of grind as a guide. Make
sure that each cutting edge receives an equal
amount of grinding to prevent an unbalanced blade.

vibration when rotating at high speeds, may cause

personal injury. Test the blade by balancing it on a
round shaft screwdriver or a blade balancer.
•
If the blade is not balanced, remove metal from the
heavy side until it balances evenly.
