Abstract: A pick axe is provided with recesses formed in the concave surfaces of its pick and its blade which are then filled with adhesive into which corresponding magnetic slugs are then bedded. The adhesive is faired with the adjacent surfaces around each recess and once set up or cured fully encapsulates the magnetic slug within its larger recess to isolate the higher frequency, or the higher energy components of each pick axe impact to protect the received slugs from demagnetization and/or fracture.
Abstract: A precision garden hoe includes a blade having a curved upper edge, a curved lower edge, pointed tips at the sides where the edges meet, and front and rear surfaces; a handle adapted to be held by a user; and a shaft having a front end attached to the rear surface of the blade, a rear end attached to the handle, and a bend so that the blade is at a non-perpendicular angle relative to the handle. The edges of the blade may be sharp. The bend in the shaft may be at an angle so that, when attached at a perpendicular angle to the front end of the shaft, the blade will be at a non-perpendicular angle relative to the rear end of the shaft.
Abstract: A solid-steel anvil of symmetrical configuration, having a top head, depending intermediate web and a base, and with the anvil being of light weight that a person can manipulatively grasp the anvil's top head with one hand to easily carry the anvil with his grasping hand, is produced by the method of providing a rectilinear elongated section, appropriately disposing the elongated section preparatory to successive cross-cuttings of the section, and cross-cutting successive lengths from the section to thereby provide a plurality of separate anvils.
Abstract: A method of making a tooth point and product wherein a tubular blank of alloy steel is heated, shaped at one end to provide a box section and shaped at the other end to provide a blade made up of two layers of steel forged together.

Abstract: A process for assembling a hand tool includes the steps of heating an elongated tang element fixed relative to the tool head, aligning a front end of a composite tool handle with a rearwardly extending portion of the tang element, and driving the heated tang element into the tool handle. The tool handle includes a thermoplastic section in proximity to the front end thereof, having an elongate tang receiving channel. The heated tang element is driven into the tang receiving channel such that as the tang element engages the tool handle, the thermoplastic section surrounding the tang receiving channel is softened and flows into intimate contact around the tang element and then hardens as the heat of the tang element is dissipated to hold the tang element in place. In one preferred form, the tang element forms a portion of the tool head which is heated and then positioned in a stationary jig.
Abstract: A method is provided which produces a head of piolet, all in one piece, by punching out a metallic blank (i.e. a long cross-shaped blank whose outline is symmetrical with regard to its longitudinal axis and comprises four parts: a peen part, a pike part, and two lateral fastening flaps) from a plate of metal, and then by the folding of that metallic blank symmetrically with regard to its medial plane, along its longitudinal axis or on both sides thereof, at least along that portion of length which corresponds to the pike. The blank is eventually shaped approximately along an arc of circle which is located along the medial plane of the blank before mounting upon the handle of the piolet.
