Manufacturing pairs of scissors, each pair including a first blade and a second blade, which are rotatably connected to one another by a fastening element, where each blade includes a front end, a rear end opposite the front end, a front portion extending towards the front end and forming a cutting element, and a rear portion extending towards the rear end and provided to support a handle, where the front portion of the first blade of at least one first pair of scissors and the front portion of the first blade of at least one second pair of scissors are designed differently, whereas the rear portion of the first blade of the first pair of scissors and the rear portion of the first blade of the second pair of scissors are designed identically.

A shears upper finger grip has a lower substantially flat inner surface arranged in a transverse plane substantially normal to a cutting plane and dimensioned and configured to enable substantially full insertion of a thumb metacarpal bone from a right lateral side and for receiving the ball of the thumb to enable the thumb to be moved to a position on a left lateral side to an orientation substantially parallel to the cutting plane and to position the hand's thenar eminence into abutment against the flat inner surface while positioning at least exterior right lateral portions of the upper finger grip in abutment against the palm beyond the hand's thenar crease and into the region of at least one of the hand's palmar creases to enable the thenar eminence and palm of the hand to oppose the forces applied by the fingers acting on the lower finger grip.

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.

Hairdressing scissors include a pair of blade bodies each having a blade portion, a middle portion, and a handle portion in turn from a tip side. The handle portion includes first and second press-formed bodies each in the shape of a flat plate and facing each other along an axial center of a pivot to extend parallel to each other along a longitudinal direction of the blade body; and cylindrical collars and first and second resin materials configured to bridge the first and second press-formed bodies. The first press-formed body includes an extension portion extending toward an associated middle portion further than the second press-formed body to be connected to the associated middle portion, and the second press-formed body is spaced apart from the associated middle portion.

A hand-held device includes a first member and a second member coupled together by a pivot point such that each member may rotate independently. The hand-held device further comprises a handle on one side of each member and a protrusion on an opposite side of each member. Further, the hand-held device may include counter-torque extensions which extend from each member such that the counter-torque extensions touch when the device is engaged.

A low-friction hub assembly for pivotally connecting a pair of scissors or lever-like members employs a pair of cooperative hub members. A first hub member has an exterior threaded surface which threadably engages with an interior threaded surface of the second hub member. Each of the hub members has annular shoulders which engage against opposed annular surfaces of surrounding aligned pivot openings of the scissors. A locking member comprising a pair of opposed pawls engages a serrated surface to lock the subassembly. A throughbore extends through the pivot assembly.
