This Tool Rest is ideal for the grinding of turning scrapers and special tools for woodcarving, e.g. large scorps and inshaves. Also for cabinet scrapers and hollowing tools. It has a generous surface, 90x110 mm (3-1/2" x 4-1/4"), which permits a safe and steady positioning of the tool towards the stone. The bore is made with a special wedge shape, which increases the locking force by 250%. You can lock the Tool Rest instantly at the chosen angle.
