  • Patent number: 9532509
    Abstract: A flower trimmer including a handle and a head connected thereto on which a blade with a cutting edge is disposed so that an end area of a flower stem brought against the cutting edge can be trimmed or cut off by a tensile force introduced at the handle. The head comprises an opening at the front end thereof through which opening the flower stem is inserted into the head substantially in the axial direction and directed past the blade. In the head, a cavity is provided next to the opening, the cavity being traversed by the blade.

  • Publication number: 20120192597
    Abstract: A leather groove forming apparatus includes: a blade holder 43 holding a blade 35 for forming a groove 9 in one surface in a thickness direction of a held leather 5 held in a flat sheet state; blade holder moving unit for moving the blade holder in an in-plane direction of the one surface in the thickness direction of the held leather 5; and blade holder positioning unit for positioning the blade holder 43 in a direction intersecting with the in-plane direction with the blade holder 43 placed on a guide member 55 in formation of the groove in the held leather 5 by moving the blade holder 43 using the blade holder moving unit.

  • Patent number: 7225647
    Abstract: A leather working tool and a method for cutting a leather strip. The strip cutting tool includes a tool head adapted for placement at least partially through the aperture formed through the sheet of material. A tool shaft is attached to and extends from the tool head. A strip cutting blade is connected to and extends parallel to a longitudinal axis of the tool head. The strip cuffing blade is positioned with respect to the tool head at a distance defining a desired strip width. The strip end is pulled between the tool head and the strip cuffing blade, and a continuous strip of a selected width is cut.

  • Patent number: 5582041
    Abstract: The tool includes a linear housing, a thin circular fleshing blade with a cutting edge around its perimeter, and a guard member. The housing encompasses an air-driven or electric motor and serves as a handle. A rotary drive shaft projects at an angle from an end of the handle, and the free end of the drive shaft is equipped to have the blade mounted thereon. The guard member is mountable on the housing to cover a substantial portion of the blade. The angular displacement of the drive shaft and blade from the handle enables the user to conduct a fleshing operation with a backhand stroke that is easier to control than a forward thrust motion.

  • Patent number: 4575902
    Abstract: A depilating appliance comprises a series of adjacent, closely-spaced hair-plucking disks driven by an electric motor housed within a casing which is designed to be held in one hand. The disks form a roller unit which is rotatably mounted behind a slot, grid or the like provided in one end of the casing. Superfluous hairs to be removed are engaged between the disks in a combing action, periodically gripped by deformation of the disks, then pulled and plucked-out as a result of rotational displacement of the disks.

  • Patent number: 4218901
    Abstract: A system, including apparatus and method for cutting leather and like flexible sheet material into straps and/or strips and for sequentially sizing and shaping the straps and/or strips uniformly, the apparatus comprising a cylindrical bar with shaping and sizing circumferential grooves in the surface thereof, a pivotable biased holder carrying a cutting edge disposed at a narrow acute angle across one or both of the mentioned grooves in the cylindrical bar so that undesired portions of the straps or strips are cut off to size and shape the strap or strip as it is forceably drawn between the groove and the mentioned cutting edge. The cylindrical bar also comprises a slot and one or more spacers to hold one or more blades parallel to each other and perpendicular to the body so that a sheet of rawhide, leather or like flexible material may be selectively and simultaneously cut into uniform strips by drawing the sheet through the parallel blades.

  • Patent number: 4127063
    Abstract: An improved leather marking tool which incorporates both the hammer and the punch into a single unit, the improvement being directed to the keying of the drive shaft of the unit in order to prevent rotation and incorporating a structure at the end of the drive shaft which permits such to cooperate with a plurality of different marking heads so marking heads can be used interchangeably.

  • Patent number: 3938452
    Abstract: A rug pointer for looping material-yarn through the apertures of backing in checkerboard pattern, and comprised generally of a manipulatable body with an adjustably extended probe and a retractile stop; the probe having a concaved notch at its lowermost terminal end adjustable to project a determined distance from the lowermost terminal end of the body; the stop having a stop shoulder and points depending therefrom in spaced relation to the probe to engage over a member of the backing to lock the yarn in position for the full extension of the loop being formed by projection of the probe with the lowermost terminal end of the body stopped against the back of the loop thus formed.
