Summary:A hone for reconditioning dental instruments of the type having a handle terminating in a blade including a planar portion bordered by a sharp edge is disclosed that is characterized by a planar abrasive surface supported upon a base alongside of which a protractor-like element is mounted for rotation. The protractor-like element displays at least one straight line whose angular relation to the abrasive surface changes as the element rotates along with a plurality of other indicia by means of which the straight line can be set at a particular angle with respect to the abrasive surface that is the same angle that the handle of the instrument to be reconditioned must bear to the latter in order for the planar and sharp edges of its blade to be properly restored as they are moved to and fro across the abrasive surface.
