What are some advantages of the Lap-Sharp® over grinders?
The Lap-Sharp® provides a flat grind, rather than a hollow grind caused by the radius of a grinding wheel. A grinder is designed to only sharpen a bevel. With the Lap-Sharp® you can flatten the backs and sharpen the bevel all on one system. Grinders are also very limited in the grit sizes offered and will not provide a finished sharp edge. The Lap-Sharp® needs few if any attachments to sharpen most tools used by woodworkers. It needs no wheel dressing as do grinders. The low speed of the Lap-Sharp® produces little friction heat and is activated by a footswitch, allowing the user to position the tool before starting the rotation of the abrasive. This provides the user much greater control of the tool and makes faceting and damage of the tool less likely.
