The invention pertains to a hand tool with a handle portion and a method for manufacturing the same.

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.

An arrangement of two rail segments, consisting of at least one mounting element disposed at each rail segment, and of at least one connector in contact with the mounting elements, by means of which the rail segments can be connected to each other at the end faces thereof, wherein each mounting element is attached to the corresponding rail segment by means of a welding seam. At least one end of the welding seam ends in a region on the rail segment outside of the mounting element.

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.

Hand tools which have an ergonomic using a palm handle and finger handle designs which achieve mechanical efficiency and ease of use. The ergonomic handle is compatible with the muscle movements of an operator using a hand tool reducing muscle strain and pain. Optionally, the palm and finger handles can have ergonomically designed cushions. In an embodiment, the finger handle can have a finger set which has a forward finger flange, a tail finger flange and a pinky grip. The ergonomic handle can also use a relief washer system to achieve a smooth low frictional resistance cutting stroke.

A portable, handheld implement for disjoining protruding concrete ties from reinforced concrete, the handheld implement adapted to apply successive bending and breaking forces to concrete ties, rebar, and the like. An L-shaped head, or chevron-shaped head, in some embodiments, receives the protruding concrete tie and coacts therewith to shear a concrete tie or rebar from a typically planar concrete surface using successive, longitudinally-applied handheld force. A concrete tie is inserted into a recess in the head of the implement designed to securely receive it. Some embodiments of the present invention comprise two L-shaped heads, on at either end of the handle.

A hammer tool includes a head and a handle coupled to the head. The handle has a first and a second connecting end fixed to the head. The handle has a first and a second medial section and the first and the second connecting ends extend from the first and the second medial sections respectively. The first and the second medial sections are disposed side by side. The first and the second medial sections form at least one first and at least one second curved sections respectively. The at least one first and the at least one second curved sections abut against each other.
