A tapered razor assembly arranged to be removably inserted into a slot disposed on a static blade member of a scissors. The tapered razor assembly includes a razor blade having a base extending from a back end to a tip end, the razor blade having a pair of side surfaces extending from the base, the pair of side surfaces arranged to terminate at a cutting edge, the cutting edge tapering from the base end to the tip end, a guard member fixedly secured to one of the pair of the surfaces, the guard having a guard end, a base, and a tip, and a cover member fixedly secured to one of the pair of side surfaces, the cover having a base and a tip, wherein the guard member and the cover member sandwich the razor blade.

The present invention relates to hairdressing scissors for preventing hair or pet fur from flying by attaching a clamp blade to an upper blade of the hairdressing scissors.

According to an exemplary embodiment of the present invention, hairdressing scissors, in which an upper scissor body having an upper blade formed on one side and a handle formed on the other side and a lower scissor body having a lower blade formed on one side and a handle formed on the other side are rotatably coupled to each other by a hinge shaft, further include a clamp blade attached to the upper end of the inner surface of the upper blade by a joining member so as to rotate with the upper blade, wherein the clamp blade has a length longer than a width direction length of the upper blade so as to come in contact with the hair prior to the upper blade, and the joining member has a predetermined thickness so that the lower blade is able to rotate between the upper blade and the clamp blade.

A pair of slide cutting shears that have identical cutting angles of approximately 53 degrees on the thumb and finger blades, and where the thumb blade has approximately only 40% of the top end of the blade sharpened and the remaining section of the working blade is radiused and cannot cut. The shears have a four finger grip, and adjustable bump stop and a tightenable pivot pin assembly to draw the blades closer.

A pair of scissors has a first cutting blade with a thumb handle and a thumb ring and a second cutting blade with a finger ring. The second cutting blade is pivotally attached to the first cutting blade, and the first and second cutting blades pivot relative to one another within a first plane. The thumb ring is slidably attached to the first cutting blade by a shaft that moves freely but with a certain amount of friction along a longitudinal slot in the thumb handle of the first cutting blade when the scissors are in use. The longitudinal slot in the thumb handle is situated within a second plane that is perpendicular to the first plane.

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.
