Abstract
Apparatus for sharpening an edge tool comprises a rotary grindstone mounted so as to be rotatable about a first axis of rotation, and a tool mount for a tool to be sharpened, in which the tool mount is turnable about an axis whereby to permit the edge tool to be turned so that a face to be ground moves in an arc lying in a plane parallel to that part of the grindstone against which the face is to be ground. The rotatable grindstone has a hollow cup-shape and is mounted at the end of a spindle in a body which can be clamped by brackets to a workbench or other support surface leaving the spindle exposed to be gripped by a pistol drill or other drive means.
