With the GROOVE SHARPENER you can sharpen your grooves sharper then factory-fresh.
Your GROOVE SHARPENER is made of heat treated tool steel which measures a hardness of 62-64 Rockwell. Because the tool is
so hard it will not loose its cutting edge like other groove tools. The tool has two sharpening ends. One end is V shape so
you can cut V shaped grooves and the other is square shape so you can cut square grooves.
