Polishing materials for dentists and dental technicians, which are called “paper cones,” are made of sandpaper rolled up into conical or cylindrical shapes. Usually an original paper cone has no shaft, and a fork end shaft sold separately is used. However, a small-sized Mini Cone is supplied with its specified fork end shaft, and other products such as Sharp Mini and Sharp Cone are supplied with an Ohki-invented wood screw type shaft exclusive to fitting. The characteristic is its sharp conical shape and strong retention with low eccentricity.
