This pink Diamonite honing stone is ideal for removing burrs from newly sharpened blades. It is made from very hard pink Diamonite stone and has had very little use. It measures 4 inches (102.00 mm) long by half an inch (12.50 mm) wide by a quarter of an inch (6.30 mm) thick. Please look carefully at photos to see exact item and condition. I am happy to combine postage if you buy more than one item.
