  • Publication number: 20100212165
    Abstract: The present invention relates to a new type of scissors for hairstylist which allows the hairstylist to optimise the cutting operations, in particular by eliminating the need to go over the tip of the locks of hair with the tip of the straight scissors or to go over the locks of hair with trimming scissors in order to move the edge of the lock of hair, which is straight when the lock of hair is cut using the straight scissors or other similar known models of the prior art. Instead, the scissors according to the present invention allows in a single cutting operation to obtain a “perfectly irregular” end of the lock of hair, obtaining an irregular line of perfect measure and combining the gripping comfort and the manageability of the scissors for hairstylists with the efficacy of a tool capable of obtaining a non-straight cut of the lock of hair, conferring in this manner a greater comfort of use and a greater efficacy to the scissors.

  • Patent number: 6637116
    Abstract: A decorative fruit cutting apparatus is provided formed from two semicircular sections and having an inner diameter the size of the fruit or vegetable to be cut up. A plurality of evenly spaced cutting blades line the periphery of the inner diameter of the assembled ring. The two ring sections are pivotally attached together at one end so that the two ring sections can freely expand and contract around the fruit or vegetable.

  • Patent number: 6129622
    Abstract: A pair of scissors for cutting shellfish cleanly and shielding airborne matter created thereby from contacting a user. The pair of scissors include a stationary blade body, a moving blade body, and a shield. The moving blade body is pivotally attached to the stationary blade body and forms therewith a scissor-like device for cutting the shellfish. The shield shields the airborne matter created by cutting the shellfish from contacting the user, and is replaceably disposed on the moving blade body which allows the shield to be removed and washed.

  • Patent number: 5758422
    Abstract: A scissors with interchangeable blades wherein first and second blade holders are pivoted with respect to each other and each has a manual graspable configuration thereon. On the other end of each blade holder is a blade retainer. Individual blades can be placed in pairs in these blade holders. These pairs of blades have different cooperative configuration so that they can make triangular cuts of different sizes, scallops of different sizes, and other repeating configurations.

  • Patent number: 5511313
    Abstract: An electric/pneumatic pinking shear with one touch button blade closure. The blades In these shears are shorter than previous blades because of the twisting and bending moments of long thin blades. The bending moments of the blades have been reduced so that shear tension between the blades can be kept to a minimum. The teeth on the blades are wider than other pinking shears in order to improve the quality of the finished cut. This will decrease the amount of thread unraveling after the fabric is cut.

  • Patent number: 4930219
    Abstract: A dual-purpose, hand-held scissors for seamstresses and other users which have two unique blades with teeth which will cut a series of proportionately-spaced, single notches (V-shaped indentations) into textile fabrics and other soft, flexible and pliable materials and trim away excess fabric from the article simultaneously. It (1) saves time by performing two essential functions in one operation; (2) simplifies clean-up after sewing because the original method was very messy as when the individual notches were cut, they would scatter everywhere as they fell away from the fabric; and (3) permits more accurately cut notches which are consistent in size and shape to give the article a neater appearance. The shape of the blades is such that upon applying the scissors into the seam allowance on garments and/or toys and crafts, etc., the seam will be trimmed smoothly for a designated distance, then a notch will be cut into the seam allowance and simultaneously trim the excess fabric at that point.

  • Patent number: 4584770
    Abstract: Pinking shears are disclosed comprising a pair of blades having cutting teeth and tips on one end and a handle on the other end, a common pivot assembly for the pair of blades, and an adjustable ball assembly for adjusting the pressure applied at the tips of the blades. The ball assembly is mounted in one blade between the handle thereof and the pivot assembly bears against the other blade to urge the blades away from one another adjacent the handles of the shears. As a result of this arrangement, the pressure between the tips is increased and a smooth cutting action is obtained when the pinking shears are being used to cut different types of materials of varying thickness.

  • Patent number: 4534109
    Abstract: A scissors has first and second arms with each arm having a finger receiving portion at one end. There is a removable metal blade having an outer edge and an inner cutting edge for each arm. A flange on each arm abuts the outer edge of the respective blade. A pair of inward projections on each flange each has a forwardly extending nose portion and a sloping rear portion and is engaged in a complementary opening in the adjacent blade. A finger extending inwardly from the forward end of each flange overlies a portion of the adjacent blade and is adapted to be engaged by the blade of the other arm when the scissors is in the closed position. A pivot structure passes through the arms and blades securing them together.

  • Patent number: 4449300
    Abstract: A pair of hair trimming shears has two pivotally connected blades with integral handles. Each blade carries a plurality of teeth which project upwardly from the surface of the blade; when the blades are closed upon one another, the tooth peaks on one blade engage the roots of the teeth on the other blade in meshing engagement. The teeth are of irregular triangular cross-sectional configuration, which produces a non-uniform, zig-zag cut line that disappears when combed. Thus, the shears permit shortening of hair length without creating undesirably defined cut lines.

  • Patent number: 4406063
    Abstract: A pinking shears having a pair of blades pivotally connected together by a bolt and having cooperative teeth formed along their leading edges and having handles at the ends of the blades opposite said teeth. A non-metallic spacer and pressure producing ridge member is located between the blades and has an apertured spacer portion through which the bolt extends and which serves to provide rough blade separation. The member also has a pressure producing ridge located at the handle side of said bolt and for bearing against the blades to produce cutting pressure between the teeth of the blades. The blades have tapered leads which cooperate with one another as the shears are closed to provide gradual smooth engagement of the blades.

  • Patent number: 4250619
    Abstract: Pinking scissors having replaceable cutting blades. The replaceable cutting blades have different edges to provide different types of pinking designs such as scallops, triangular sections, rectangular edges and the like. The replaceable blades are of rigid L-shaped construction one side serving as a base fitting against the supporting stem of the scissors and the other side having a cutting edge. Stop means are provided for registry on the supporting stems which are bifurcated and spaced apart to provide for easy reception of the replaceable blades. A special feature resides in the provision of a reversible cutting blade with both edges of the L-shaped sections having a pinking cutting edge. When not in use one section with the pinking edge serves as a base and when desired to provide a different design the blade may be removed and reversed with the unused portion serving as cutting edge and the section previously serving as a cutting edge used as a base fitting against the support stems.
