A hammer is provided that includes a handle, a head, a striking insert, and a claw. The hammer provides for a head with a keyed hole to couple to a keyed projection on a striking insert. The head also includes a dovetail projection that couples to the dovetail connection of the claw. Each component may comprise a different material. For example, the striking insert and the claw comprise one material, and the handle and the head comprise another material. In some embodiments, a slotted punch with a magnetic retainer creates a bore through the face of the head and the striking insert to support a fastener (e.g., a nail) within the head.

Disclosed embodiments include a two-shafted multi-tool including a primary shaft having a D-handle at one end and a releasable tool connector at the opposite end, and a secondary shaft having a D-handle at one end and a rotating connector at the opposite end, and wherein the rotating connector couples the secondary shaft to the primary shaft substantially adjacent to the releasable tool connector. Further disclosed embodiments include at least one adjustable shaft handle that is releasably couplable to either the primary shaft or the secondary shaft.

The invention is directed to a weapon or tool head that has an appearance that mimics chipped stone weapon- or tool heads used in prehistory and history. The weapon or tool head has an outer body portion having the desired “ancient” appearance and a hard insert is provided with at least one sharp edge exposed for use, the latter providing modern performance characteristics to the weapon or tool.

The present invention consists of a safety protective cover for cutting tool head having a protective housing fitted to receive a shape of the cutting tool and the rear portion has a locking mechanism fitted to be inserted inside a hole of the cutting tool. The locking mechanism has at least two locking arms capped at their end by a notch extending outwardly away from the other arm, and each arm comprises at least one rib on the inner surface thereof; and, further, the locking mechanism has a first side opening, a second side opening, a stop opening and a central opening; and has at least one rim on the inner surface of the central opening.

A handle connecting part comprising a recessed surface below a top surface; a head connecting part comprising an opening, a lock comprising arms extending from a cap, each arm terminating in an inward finger, with a length La of the arms from a bottom surface of the cap to a top edge of the fingers respectively and the length Lu of the top surface of the handle connecting part, above the recessed surface, are selected in such a way that when the bottom surface of the cap abuts on the top of the head connection part, the fingers of the lock reach the second recessed surface below the first surface; the handle connecting part being locked within the opening of the head connecting part by resin.
