A cutting tool includes first and second blades attached to each other by a joint, and first and second handles. A first inlay having a protruding end protrudes into a hole in the first blade. A shaft has a first end joined to the protruding end of the first inlay, and has a second end with at least one transverse shoulder. A second inlay has a protruding end protruding into a hole in the second blade and a hole receives the second end of the shaft, and an engaging surface engages with the shoulder of the shaft. The hole of the second inlay has a shape and width allowing the second end of the shaft with the shoulder to pass into the hole in a release position, but prevents the shaft and shoulder from passing through the hole when the shaft and second inlay are not in the release position.

A hand tool includes a first jaw; a second jaw rotatably coupled to the first jaw, the second jaw including a first set of projections and a first bearing surface, the first bearing surface having a first curvature; and a lever coupled to the first jaw, the lever including a second set of projections and a second bearing surface, the second bearing surface having a second curvature. During a movement of the first and second jaws from a full open position to a full close position, the first and second sets of projections are at least partially engaged to prevent a slippage between the first and second bearing surfaces that are in a rolling contact during the movement of the first and second jaws from the full open position to the full close position.

The present invention relates to scissors, more specifically to a distance adjusting device for scissors that is configured to have a fixing part passing through an open portion of a first scissor blade and a second scissor blade to couple the first scissor blade and the second scissor blade to each other, a pair of ball bearings adapted to allow the fixing part to be inserted thereinto, a thrust bearing disposed between the pair of ball bearings, and pressurizing bars inserted into one side of the first scissor blade to pressurize the thrust bearing.

Scissors, especially surgical scissors, having first and second elongate members each having a handle portion and a blade portion and being connected by a pivot between the handle portions and the blade portions for relative pivotal movement generally in a cutting plane during a cutting stroke. At least one of the handle portions supports a channel member having a length that extends toward, embraces and extends beyond the handle portion of the other elongate member to restrain movement of the handle portions out of the cutting plane and thus to resist relative lateral movement of the blade portions away from each other during the cutting stroke. The scissors are robust and are able to cleanly, effectively and accurately cut tough or slippery items which might otherwise cause the blades to splay away from each other.

A scissor cutter includes first and second pivot portions, two first offset portions, two second offset portions, a first cutting portion having a first contact face, and a second cutting portion having a second contact face. The first and second contact faces contact each other along a shear plane. The second pivot portion, the first cutting portion and the first offset portions are located at a first side of the shear plane. The first pivot portion, the second cutting portion and the second offset portions are located at a second side of the shear plane. When the first and second pivot portions pivotally move with respect to each other, the first offset portions respectively abut against the second offset portions.
