The adjustment device further includes a first stop fixed to one end of the connector and arranged in contact with the outer surface of the second cutting blade, and an adjustment means located at the opposite end of the connector and arranged to apply a pre-tensioning force on the outer surface of the first cutting blade and maintain first and second contact surfaces of the first and second cutting blades in contact.

Abstract: A scissors assembly for cutting objects is provided. The scissors assembly comprises a first blade and a second blade each having a first end and a second end with the first ends being sharply pointed. A pivot connection connects the first blade and the second blade. A serrated cutting edge is formed on the first blade between the first end of the first blade and the pivot connection and a plurality of serrated grooves formed on the second blade between the first end of the second blade and the pivot connection. The sharply point first end of the first blade and the sharply pointed first end of the second blade creates a precision point. Upon pivoting of the first end of the first blade toward the first end of the second blade, the cutting teeth of the serrated cutting edge of the first blade interfit with the serrated grooves on the second blade.

Abstract: 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.

Abstract: A cutting tool includes a metal plate including a blade that forms a cutting jaw with an anvil, the metal plate being connected in an articulated manner to an anvil part at a first pivot point and connected operationally to a first elongated element for opening and closing the cutting jaw in response to the relative turning movement of the first elongated element and the second elongated element about the second and the third pivot points respectively.

Abstract: A pruner has a movable handle/blade assembly pivotally coupled to a static handle/blade assembly by a pivot assembly carried by the static handle. The pivot assembly further has a bush within the static handle and on which the movable handle/blade assembly is pivotally mounted, a spring for pivotally biasing the movable handle/blade assembly to an open position being retained by the pivot assembly within the static handle. Both the movable blade and static blade are mounted on the bush and are clamped laterally between two separate parts of the bush which are assembled together in screw threaded engagement, and the two blades are supported from the bush by a bearing ring of low friction material.

Abstract: A cutting apparatus for easily opening plastic packaging comprises: first support member 100, second support member 200, first shaft 400, second shaft 401, third shaft 402, first cutting wheel 300, second cutting wheel 301, third cutting wheel 302, handle 303, first drive wheel 304, and a second drive wheel 305.

Abstract: A flexural pivot joint includes two pivoting members, which may be levers of a pivotal hand tool, and two substantially identical flexible blade elements, each substantially Z-shaped and having opposite ends respectively connected to the pivoting members. In particular, each blade end has an enlarged coupling portion adapted to be press-fitted in a groove which may be formed either directly in the lever member or in a bushing which is fixed to the lever member. Each bushing may be either a full cylinder or a split cylinder. In one embodiment the joint includes, in addition to the Z-shaped elements, two non-identical flexible elements, the four elements being equiangularly spaced. The grooves and coupling portions may be complementarily shaped, with each groove having a bead receivable in a recess in the coupling portion to inhibit relative rotation.

Abstract: The present invention relates to tools such as scissors, shears, pruners, and the like, which are resiliently biased to an open position, and which have a locking mechanism to keep these tools in a closed configuration. More particularly, this invention is concerned with tools having a pair of cooperatively engaging members provided with a resilient lock slidable within slots formed in these members. The lock includes a button having a yieldable head merging into a shank extending through the slots, the shank being joined to a cap. The head and cap have concavely shaped faces so that they are effectively in contact with the tool in respective annular regions of the tool, the area of these regions being proportional to the degree of compressive force applied to the lock.

Abstract: Disposable scissors for medical use comprising two plastic handles, two shaped stainless steel blades disposed between the handles and in contact with each other, pivot means coupling the handles and the blades, characterized in that the part of each handle through which the pivot extends defines an integral extension extending from the pivot outward over part of the blades to support and apply pressure thereon during the shearing movement.

Abstract: A cutting device comprising first and second members each comprising a blade at one end and a handle at the other end, a pin on which the first and second members are pivotted so that the blades work with a scissor action for cutting purposes, and a clip which extends longitudinally along an outside face of one of the first and second members, the cutting device being such that the first and second members are retained on the pin between an abutment part at one end portion of the pin and the clip, the clip slides in a groove at the other end portion of the pin, the clip comprises a projection engaged in a complementary recess in one of the first and second members so as to hold the clip in a locking position on the pin, the clip further comprises a flat strip having at one end a slotted portion and at the other end the projection, the strip being bent on itself to define a limb parallel with the slotted portion and further bent so toward the slotted portion such that the projection extends substantially ortho

Abstract: The invention relates a means in scissors for balancing the closing force of the scissors. It comprises a wave-shaped spring washer clamped between the head of the scissors rivet and the shear blade, at least one of the contact surfaces being wave-shaped and provided with the same number of waves as the spring washer.

Abstract: A pair of scissors with an adjusting mechanism comprising a bolt to be inserted through openings of blades of the scissors, a fastener engageable with one of said blades, a means for keeping said fastener to be engaged which said blade, and a nut being put around said bolt, said nut being engaged with said fastener, whereby the nut will rotate either to tighten or to loosen the blades by rotating the fastener.
