An Apparatus defined as a bolt with large washer and lock washer and an alloy connecting bar mated together with its specifically designed wooden handle. The apparatus is mated together in the assembly process. With the striking tool head in position on the wooden handle the bolt assembly is screwed into an alloy bar which has been placed in the wooden handle. The bolt is then tightened which pulls the striking tool head into a tight wedged position.

A tool is provided that includes unitary plate that includes a blade portion and a tang portion. The blade portion can include an edge. The tang portion can include a positioning hole, a first hole, a slot, a second hole, a rivet hole, and one or more teeth (also referred to as one or more barbs) on a side of the tang portion. The tool can further include a hilt member which includes a through passage, a tab, and a notch. The tool includes an overlay on a body to create a handle for gripping the tool. The tool further includes a hammerhead cap on an end of the body, the hammerhead cap is coupled to the handle with a rivet through the rivet hole.

A handle includes an inner core and a gripping portion disposed around the periphery of the inner core, and at least one chamber is formed between the inner core and the gripping portion. A hammering tool includes the handle. When the hammering tool is used for striking, the internal damping slot of the hammerhead can use a damping material as a first buffering and absorb the vibration and impact force of the hammerhead, which are then delivered to the inner core of the handle, the inner damping layer and its chamber serve as a second buffering and absorb the vibration and impact force delivered from the inner core of the handle, and finally, the outer damping layer serves as a third buffering and absorbs the vibration and impact force delivered from the inner damping layer.

An adjustable tool holder is configured for interchangeable use with a variety of tools provided with different connection elements. The connection elements include at least a first connection element configured for a first manner of connection with the tool holder and a second connection element configured for a second manner of connection with the tool holder. The tool holder includes a distally extending tool support operable to detachably support each of the tools. The tool support includes a first tool connector configured to releasably connect with the first connection element in the first manner of connection. The tool support includes a second tool connector configured to releasably connect with the second connection element in the second manner of connection.

A hair brush with double-sided comb teeth includes two comb teeth portions with different types of comb teeth arranged and implanted on both upper and lower surfaces of an elastic clip cushion of the hair brush respectively, and a multiple of through holes formed at the periphery of the elastic clip cushion and provided for positioning. With the effects of a brush handle and a cover frame, the elastic clip cushion is clamped at a receiving slot of the brush handle, and the total area of the elastic clip cushion is slightly greater than the area of the receiving slot of the brush handle, and one of the end surfaces of the elastic clip cushion may be arched into an arc shape and the other end surface is naturally formed into a corresponding arc recession. The comb teeth portion with the arched surface is used as a hair brush, and the comb teeth portion with the recession is situated in a concealed status. When a user wants to switch the comb teeth portions, the user simply applies an appropriate pushing force to change the originally ached end surface into the recession, so as to complete the switch of the comb teeth portions.

A multipurpose tool system that can be assembled into multiple configurations by a user. The tool system may comprise a plurality of components, including tool heads, shaft segments, and handle ends. The components of the tool system can be combined in various configurations to provide different functions, at different lengths. Connectors may be utilized to connect the various components of the system using a twist lock mechanism. The connectors may include a tubular sleeve member having a biased locking shaft that interacts with a locking groove.
