Abstract: A surface mounted sharpening tool having a generally rectangular body which may be formed of one or two sections and which body has blade cavity structure with sharpening blades forming a V-shaped sharpening notch. The body includes a pair of generally parallel guide ridges extending outwardly from the body such that a guide slot is defined between the two ridges or in which the guide slot may be recessed into the body. The guide slot through which the tool to be sharpened is guided is set at a predetermined angle from a right angle to the flat surface of the blade in order to obtain the most favorable sharpening action.

Abstract: Hand held sharpening device for tools and instruments having single cutting edge type blades such as lawnmowers and the like. A hand grip body has a forward nose section in which is located a recess for a single blade having two sharpening edges. A retainer member attaches to the body and holds the blade in the recess. The retainer member and the cutting edges of the blade extend beyond the front end of the nose such that two sharpening slots are defined. The device is also provided with a hand guard.

Abstract: Drill bit construction having a removable lead screw and a drill body with a work face comprised of two planar surfaces which geometrically intersect on a diameter line such that the angle between the two surfaces is approximately 170.degree.. A cut-away segment is formed on each side of the body with each of the segments having a cutting edge in the form of a detachable blade which is also provided with a cutting spur on the outer end. The body itself is detachably removable from the drill shaft or shank. The body is also provided with a removable lead screw or guide point.

Abstract: Drill bit construction having a removable lead screw and a body which has a conically shaped work facing surface. With generally triangularly shaped cut-away segments. Each of the segments has a cutting edge either in the form of a detachable blade or integrally formed into the body. The body itself is also detachably removable from the drill shaft or shank. In smaller diameter embodiments a spiral member recedes from the shaft adjacent the head for removing shaving as the bit proceeds through the wood.
