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

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.

An apparatus and method to secure a bolt cutter, wire cutter, cable cutter or other type of pivot handled tool with two protruding tabs whose apertures align with each other as the handles of the pivot handled tool enter a closed position. A shackle of a padlock may be inserted through the aligned apertures to lock the handles in the closed position.

Disclosed are scissors, which comprise handles and scissors heads, the handles comprising a first handle and a second handle, the scissors heads comprising a first scissors head and a second scissors head, the first scissors head being provided with a first blade and extending from one end of the first handle, the second scissors head being provided with a second blade and extending from one end of the second handle, and the first scissors head being pivotally hinged to the second scissors head via a pivoting structure, wherein the first scissors head and the second scissors head have a small width to thickness ratio at the connection between the scissors heads and the pivoting structure. The scissors greatly increase the rigidity of the scissors head, enhance the shear-compression intensity of the scissors, facilitate the cutting of thick objects, and meet the requirements of various objects to be operated.

A pipe shears includes a base, a ratchet plate pivotally connected to the base, a cutter blade detachably mounted to the ratchet plate, a positioning member mounted between an elongated hole of the ratchet plate and a positioning groove of the cutter blade, and a push rod inserted in the base and stopped against a stop member. When the push rod is not pushed, it is positioned in the elongated hole of the ratchet plate and stopped against the positioning member to force the positioning member into engagement with the positioning groove of the cutter blade, and the cutter blade is not detachable at this time. When the push rod is pushed, the stop member is moved out of the elongated hole of the ratchet plate to unlock the positioning member from the positioning groove of the cutter blade for allowing removal of the cutter blade.
