  • Publication number: 20080155836
    Abstract: The invention relates to a method for manufacturing barber scissors, wherein the scissor blades are pre-shaped from blanks by a predetermined degree of curvature in the direction facing away from the edge. This is followed by a step of welding on a hard metal material in the form of a welding bead on respective mutually facing faces of the scissor blades in order to form the edges, wherein the preliminary curvature of the scissor blades is neutralized owing to the influence of heat during the welding process. Subsequently the welding beads are ground so as to form the edges, and the scissor halves are pre-set and hardened. Then the barber scissors are hard-set in the assembled condition. The invention furthermore relates to barber scissors having such a configuration. Here the edges are present as massive material over the entire thickness of the scissor blades, so that even severally repeated re-grinding or re-setting of the barber scissors is possible without any loss of functionality.

  • Publication number: 20040159197
    Abstract: An apparatus and a method are disclosed for cutting cable. The apparatus has an elongate handle having a first end and a second end, and the first end has a first jaw member. A second jaw member pivots about the handle to form a set of jaws moving between an open position and a closed position. The set of jaws has a first cutting surface opposite a shaped supporting surface that receives and holds the cable being cut. The first cutting surface cuts the cable when the set of jaws is moved to the closed position. A channel in an outer surface of the apparatus includes a second cutting surface protruding from the channel for slitting an outer sheath of the cable. Wherein the cable is laid in the channel and, as the cable is pulled along the channel, the second cutting surface slits the outer sheath of the cable.

  • Patent number: 6751870
    Abstract: An instrument for cutting hair comprises first and second members extending longitudinally in a direction generally parallel to a hinge axis 19 of a hinge that connects the two members. Each member has an arm and a leg. The legs have sockets in which tools are received. The arms comprise grip portions for grasping and actuating by a user's hand. During use, the actuation of the arms moves the legs in an arcuate path of a common circle about the hinge axis 19. The legs and the tools disposed in the sockets of the legs have straight features that remain parallel to each other and to the axis 19 of the hinge during movement along the arcuate path. The instrument has a closed pinching or clamping position in which the tools meet each other in abutting relation.

  • Patent number: 6748662
    Abstract: A hairdressing scissor assembly includes at least two pair of scissors each having a first scissor element and a second scissor element pivoted to the first scissor element. Each of the first scissor element and the second scissor element includes a handle. A first engaging element is formed on a first side of a first connecting member and releasably engaged with a side of one of the handles of one of the pairs of scissors. A second engaging element is formed on a second side of the first connecting member and releasably engaged with the other side of one of said handles of the other pair of scissors. The first connecting member can be replaced by a second connecting member having a thickness different from that of the first connecting member, thereby allowing a change in a spacing between the pairs of scissors.

  • Patent number: 6725544
    Abstract: This creation is to provide a kind of anvil structure improvement for garden clippers. Such anvil is installed at the end of garden clippers' first handle, allowing the moving blade at the end of the second handle to oscillate into contact against the inner anvil surface of that anvil. The inner side of that anvil is a flat surface, the tip of which is in a position of jutting out from the tip of the moving blade. The anvil features a first cutting edge at the anvil's outer side, and a second cutting edge is further installed at the tip of the anvil. The provision of such first, second cutting edge adds extra functions of cutting, digging and drilling to the garden clippers as their primary applications.

  • Patent number: 6698099
    Abstract: A convertible knife assembly includes a knife and a conversion piece. The knife includes a blade with a handle end portion, a tip, a cutting edge intermediate the handle end an the tip, and a spine opposite the cutting edge. The conversion piece has a spine-opposing portion and a handle portion such that the conversion piece is adapted to be mounted on the knife pivotally with the spine-opposing portion opposing the spine of the blade and the handle portion opposing the handle of the knife. The action of a user squeezing the handle portion of the conversion piece and handle of the knife toward each other causes the spine-opposing portion of the conversion piece and the spine of the blade to move toward each other in order to bear against an object the user positions between the spine-opposing portion of the conversion piece and the spine of the blade.

    Abstract: Occupational disorders including pain in hand and stiff shoulders to be caused by using scissors, which are giving rise to problems in the barber and beauty industry, can be lessened or prevented. The scissors are highly versatile to be capable of coping with diversity of cutting techniques. In the scissors, the leg of the movable blade can be divided into the ring side leg portion and the blade side leg portion, and the position of the ring to which the thumb is inserted can be adjusted freely by loosening and fastening the connecting screw depending on the size of the hand and the length of the thumb. Further, the leg of the movable blade is provided with a pair of finger-inserting rings, and the leg of the fixed blade is provided with one such ring. With these total three finger-inserting rings, the scissors can be used in a manner totally different from the usage of the conventional scissors to cope with diversified new cutting techniques.
