For the precise work with abrasives and polishers personalised shapes are often preferred to the existing range. Also sharp edges or curves are worn down, so that the instrument is not longer used, even though there still is enough material on the shank. The diamond impregnated Abrasives Dresser for ceramic bonded stones and polishers and the SHOFU Adjuster from aluminium oxide for the Dura-Green DIA instruments enable easy shaping of edges and curves, as well as cleaning of the instruments.
