A garden shears has a first cutting member, a second cutting member and a protecting member. The first cutting member and the second cutting member are combined adjacent to each other, and the first cutting member and the second cutting member respectively have a blade portion facing the blade portion of the other cutting member. The blades of the first cutting member and the second cutting member are used for opposite positioning cutting, instead of staggered cutting after closing, which can avoid the formation of two different cut surfaces on both sides of the branches. The protecting member has a securing aperture and an arced slot, and the securing aperture is a polygonal aperture with multiple engaging edges.

The present invention is an improved design for shears that allows for cutting through gauze or bandages. The inventive shears include first and second levers mounted one to the other by a pivot joint so as to form a fulcrum substantially mid-way along their lengths, and wherein a first end of one of the levers are formed as a shearing blade and wherein the second ends of both of the levers are formed as looped handles mounted on the ends of corresponding stems. The first lever has a cutting edge along one side of its length, with a facing edge of the second lever being blunt, the levers allowing for shearing engagement of the cutting edge over the blunt edge as the levers are rotated relative to one another about the pivot joint between an open position wherein the cutting edge and blunt edge form a V-shaped crease for receiving in the crease an object to be cut, and a closed position wherein the cutting edge substantially overlaps the blunt edge. The second lever has no sharpened edges or points and has an inclined profile from its tip to the pivot joint allowing the second lever to more effectively lift away any material to be cut.

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.

In opening and closing scissors, separation between both blades caused by inclination of one blade body relative to the other blade body is prevented or reduced. Specifically, with a head being in contact with a movable blade, a coil spring comes into contact with a head at one end and with the bottom of a counterbore at the other end. This pressing force allows a stationary blade to tightly abut on the movable blade. A taper face is formed at the stationary blade side of the head to press and expand the one end of the coil spring radially outside a pivot.

A joint for a cutting tool includes a bolt with a head in a first end, with a thread in a second end, and with an intermediate section between the first end and the second end, which during attachment of two objects rotatably to each other protrudes trough openings in said objects. A nut is received on the thread. In order to provide an easy solution for adjusting the tension of the joint and at the same time preventing accidental loosening of the joint, the bolt is provided with a cavity. An expansion bolt with a threaded end protrudes into the cavity and expands the second end of the bolt.
