Abstract: An apparatus for sharpening tools includes a sliding tool holder permitting correct positioning of a tool face relative to a planar abrasive surface and the application of uniform pressure to the tool face for accurate grinding of the bevel that defines the cutting edge.

Abstract: An inexpensive and easily used gauge for accurately gauging the position of a tool is described. The gauge includes at least one fixed or adjustable gauging reference positioned relative to the table or other work locating datum of the power tool. The gauging reference has a conductive surface to be brought into contact with the working element of the tool. A gauge for measuring the angle of a tool is also described with a gauging reference that contacts the tool in a plane parallel to the plane of motion of the working elements of the tool. An LED and battery are connected in series and to the gauging reference and to a second contact node. The second node of the normally open circuit is insulated from the gauging reference but arranged for contact with a conductive path to the working elements of the tool. When the gauging reference and the contact are in conductive engagement with the tool an LED emits light indicating that the working element of the tool is in the correct position.
