An axe including: a lever axe head having a cutting edge, the lever axe head being configured to generate a torque and to rotate upon one of the cutting edge striking a material and the cutting edge penetrating a predetermined distance into the material; a handle having a first portion attached to the lever axe head and a second portion to be gripped by a user; and one or more springs disposed between the first portion of the handle and the lever axe head for biasing the lever axe head and handle relative to each other such that first portion of the handle and the lever axe head rotate relative to each other to absorb at least a portion of the generated torque from being transmitted to the user.

A handheld tool configured to procure fuel is described. Embodiments of the fuel procurement tool include a handhold having a cutting mechanism located proximate one end of the handhold. Typically, the cutting mechanism can include at least one cutter link having a depth gauge, a top plate, and a gullet formed between the depth gauge and the top plate. The fuel procurement tool can be implemented to procure kindling from a piece of wood.

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. This may reduce noise and the loss of energy.

A combination tandem cutting ax head and adz is disclosed that is adapted to firefighting. The ax may include a front end that is divided between a concave portion and a flat section. The concavity creates edges for cutting through surfaces, while the flat section functions to hinder the ax head from becoming wedged in the material. An adz may be provided in which the fulcrum is raised above the head and located between the handle and the adz edge, which increases the lever arm.

A hand tool comprising a head portion, a shaft, and a grip component is provided. The grip component and the shaft form a handle of the hand tool. The grip component is a reverse-molded component formed by: forming the external portion of the grip component by molding a first thermoplastic elastomer (TPE) material or thermoplastic urethane (TPU) material into a shell that surrounds a first cavity; after forming the external portion; placing the shaft into the first cavity; and, after the external portion is formed and the shaft is placed into the first cavity, forming the inner portion of the grip component by injecting a second TPE material or TPU material into the first cavity and onto the shaft. The first TPE or TPU material has a first level of hardness, and the second TPE or TPU material has a second level of hardness lower than the first level.
