A hammer tool includes a head and a handle tightly coupled to the head. The head defines a through hole and a hole connected to the through hole. The hole extends transversely to the through hole. The through hole is of a first width and the hole is of a width greater than the first width. The handle includes a connecting end inserted through the through hole. The connecting end is extruded after inserting through the through hole to include at least one positioning protrusion protruding into the hole. The connecting end is of a second width at where the at least one positioning protrusion is disposed. The second width is greater than the first width.

Striking tools are disclosed that include an aluminum head. Striking surfaces may be securely attached to the head by a bushing or other means. In this way, light weight striking tools may be made with greater durability.

A tool includes a handle portion, a head portion at an end of the handle portion, a hammer strike surface at a forward region of the head portion, an upper extension and a lower extension of the head portion extending away from the head portion, defining a gap between the upper extension and the lower extension, and a blade formed in the head portion, recessed within the gap between the upper extension and the lower extension.

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.

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.

A door opening system includes a trailer that has a door and the door has a door handle. A tool is provided and the tool may be manipulated. The tool has a striking surface to strike an object when the tool is swung at the object. The tool has a gripper and the gripper engages the door handle thereby facilitating the door handle to be manipulated. The gripper has a functional width of at least thirty two mm. The tool has a first hook to engage a device thereby facilitating the device to be remotely manipulated. The tool has a tapered end to engage a ratchet thereby facilitating the tool to rotate the ratchet.

A hammer tool includes a hammer head and a handle. The hammer head includes an insertion hole and first and second side holes aligned with each other and located on two opposite sides of and intercommunicating with the insertion hole. The handle includes an insertion portion on an end thereof. The insertion portion is inserted into the insertion hole. A first coupling flange is integrally formed with the insertion portion and is inserted into the first side hole. The handle includes a hollow portion extending in a longitudinal direction thereof. The handle further includes a third side hole extending in a radial direction thereof Δn end of the third side hole intercommunicates with the hollow portion. Another end of the third side hole extends to an outer periphery of the insertion portion. The third side hole is aligned with the second side hole.
