A hand tool has a handle, a first working portion, and a second working portion. The hand is elongated and has a top. The first working portion and the second working portion are detachably connected respectively with two ends of the top of the handle. Each one of the first working portion and the second working portion is made of a material different from a material of the handle.

A force-limiting and damping device has a body, a tapping element, and an elastic element. The body has a connecting segment and a holding segment. The connecting segment is formed on an end of the body and has a mounting hole. The holding segment is formed on the body opposite the connecting segment. The tapping element is connected to the body to move relative to the connecting segment. The elastic element is mounted between the tapping element and the connecting segment to abut against the tapping element and to enable the tapping element to move relative to the connecting segment. The structural relationship between the connecting segment, the tapping element, and the elastic element may provide a delayed rebound and damping effect to the reaction force, and the applied force is continuously transferred to a tapping object, and this may reduce noise and the loss of energy.

A striking tool disclosed herein includes a body having a first lateral side and a second lateral side opposite the first lateral side. The striking tool further includes a handle including a shank. The body is integral with the shank. The striking tool also includes an implement including a bracket. The bracket abuts a butt end of the body and the handle and overlaps a portion of the first lateral side of the body. The striking tool further includes a fastener extending from the first lateral side toward the second lateral side and through the bracket.

A hammer has a claw assembly that is linearly moveable relative to the head of the hammer so as to improve leverage and range of prying for nail removal. A locking mechanism secures the claw assembly in a position. The locking mechanism may be automatic or manual, and may comprise a ratcheting mechanism with a pawl and rack, or a clamping mechanism with a deflectable sleeve and engaged bar, or a biased pin lock mechanism.

A striking tool having an improved attachment mechanism to safely and securely attach the head of the tool to the tool handle. In one configuration, the attachment mechanism has a key at the upper end of the handle that is sized and configured to be received in and engage a cooperatively configured keyway on the lower side of the head. In another configuration, the attachment mechanism has a connecting element with an elongated body that extends through a tubular body portion at an upper section of the handle and into a passageway in the head. In yet another configuration, the striking tool has both attachment mechanisms. A striking member made out of harder material can be utilized for the striking portion of the head. The connecting element can connect to an aperture in the striking member. A side nail puller can be positioned on the outer surface of the handle.

The present invention is a manual nailing tool configured to provide a user with improved functional advantages over prior art hammers. It manually drives a substantial or predetermined amount of a fastener, such as an 8.89 cm (3 inch) common nail, into a work piece with one hand using one striking action. The unique configuration of the integrally formed nail-starter and angled strike face closely combines the nail-starter function with a full force, sustained first strike on the nail head. The hammer is also configured with a unique head shape and strike face to improve striking power and facilitate a stronger and more direct impact force on the nail head.
