Abstract: A non-stick knife for daily use comprises a handle; a metal piece attached to the handle; a wavy blade on the upper edge of the metal piece at the distal-end from the handle, with the section of the wavy blade being a wedge; a second blade at the bottom of the metal piece, with an arc shape part at the near-handle end for bone chopping; a crimped isolation groove above the center of the second blade on one side of the metal piece; and a slide for separating the materials which the knife cuts from the crimped isolation groove. This knife has the improved features of non-stick, bone cutting and chopping compared with the regular knives.

Abstract: The present invention relates to a cleaver (8) having a crush-forged crank (6). In order to provide a cleaver having an improved manageability and surface feel, thereby preventing any possible injuries during the use of the cleaver, the invention proposes that the crank according to the invention extends from the handle (4) in the direction of the cutting edge (11) along the blade and/or edge surface (5) on the handle side.

Abstract: A device for cleaving optical fibers is provided. The device includes a housing assembly having an opening therein for receiving an optical fiber to be cleaved, and housing bending and cutting members which are reciprocally moveable in a direction transversely and substantially perpendicularly to the longitudinal axis of an optical fiber inserted into and through the opening into the housing. The housing assembly optionally has a removably connected receptacle for receiving the cut ends of a plurality of cleaved fibers.

Abstract: A process for releasably attaching a tool handle to a tool head includes the steps of (1) inserting an end of the tool handle into the tool head through a tool head aperture, (2) turning the end of the tool handle relative to the tool head to engage a pair of lands therein which prevent withdrawal of the end of the tool handle from the tool head, and (3) threading a nut onto the tool handle so as to engage a portion of the tool head adjacent to the aperture. The process is accomplished by providing the handle a connecting stud at one end thereof, wherein the connecting stud includes a pair of oppositely disposed flanges which extend generally perpendicularly outwardly therefrom. The tool head has a central cavity into which the connecting stud is inserted through the aperture. The pair of lands are capable of selectively engaging the connecting stud flanges to prevent withdrawal of the connecting stud from the tool head.

Abstract: A knife comprising a blade and a handle adapted to be grasped with a hand. The blade comprises a body having a proximal and a distal end. A longitudinally-extending tang is disposed at the proximal end of the body to attach the handle to the body of the blade. The blade has a sharp cutting edge on a first margin and a flat edge on a second margin. The second margin is on the opposite side of the body. The first and second margins merge together at their distal ends to form a tip. The tip has a sharp cutting edge on each margin. The first margin has a serrated portion between the cutting edge on the tip and the cutting edge between the proximal end and the sharp cutting edge on the tip. The first margin is bowed outwardly between the proximal end and the distal end. The second margin extending longitudinally from the proximal end for a predetermined length and then bends obliquely for a second predetermined length to terminate in the tip.

Abstract: An optical fiber cleaver is disclosed wherein a blade applies a pre-set force to an optical fiber to form a notch in that optical fiber. In a preferred embodiment, a spring applies a pre-set force to the blade such that should an undue amount of force be applied to the fiber from the blade, the blade will overcome the spring force and not move towards the fiber any further. The cleaver is preferably formed from two pivotally connected handle portions each including holder portions which come into mating contact with each other to provide a stop against further pivoting movement. At that time, the blade is forced into the optical fiber to cleave the optical fiber. In a further feature of this invention, an optical fiber guide provides a stop between an insulated portion of the optical fiber, and a stripped portion. The optical fiber guide is adjustable to adjust the distance between the end of the insulation and the location of the notch.

Abstract: A device for removing unwanted vegetation consisting of a pole with a pair of cutting members on one end and two control handles on the other end. In use, the end with the cutting members is pulled through the vegetation and as the device moves, the offending vegetation is cut off by the cutting action produced by the pulling movement. If, during the cutting, the unwanted vegetation is found to be supple and yielding, a first handle is depressed. This brings the cutting members closer together and causes the supple vegetation to be sheared off. On the other hand, if, during the cutting, the unwanted vegetation pulls out of the ground and becomes lodged in the device, a second handle is depressed. This permits the cutting members to rotate away from each other thereby releasing the unwanted vegetation from the device.

Abstract: The present invention relates to apparatus for cutting carcasses, especially hogs. The apparatus comprises a knife to which is imparted an oscillating motion in the vertical direction. This is suitably accomplished by a ramming device arranged at one end of the knife with the knife being pivotably supported by a frame on its opposite end.
