ABSTRACT:
A method of increasing the length of time a tool maintains sharp cutting edges utilizes the steps of manufacturing the tool with the cutting edges ground sharp and then partially dulling, to a lighter or heavier extent, those previously ground sharp cutting edges. Often the partial dulling is accomplished by means of applying a brush wheel to the selected cutting edges.
