Video tutorial on how to sharpen a metal chisel. After usage a chisel can either dull or chip which does not make it work as efficiently as it should. A chisel can be resharpened to make it functional again, there is no need to throw it away. Make sure you wear safety glasses when doing this procedure. An angle gauge can be used, but is not necessary. The more practice you get, the better you will become at sharpening center punch.

The tip angle of a center punch should be about 60 degrees, this ensure it will work correctly and have a long life expectancy.
When sharpening, the grinder wheel must turn in such a manner where it'll pull the material away from the tip. Ensure that you flip the chisel over to keep the tip centered and be careful not to overheat it so it does not wreck the temper of the metal. Also when sharpening, move the chisel along evenly on the grinding wheel which ensures even wear on the grinding wheel.
