Offset Blade And Handle Patents (Class 30/257)
  • Patent number: 10046467
    Abstract: Provided is a pair of scissors, which can cut an object efficiently with lighter force, and makes it easy to cut a cardboard and the like since the pin joint does not hinder the cutting. The pair of scissors comprises: a first handle portion operated by a thumb; a second handle portion operated by other fingers; a first blade portion which connects to the first handle portion; and a second blade portion which connects to the second handle portion; first and second protruding portions which protrude the first blade portion and the second blade portion to the second handle portion side from a position where the first blade portion and the second blade portion intersect each other; and a pin joint that rotatably joins both of the first protruding portion and the second protruding portion to each other.

  • Publication number: 20140033543
    Abstract: Kitchen scissors are curved and have a single or multiple blade for safer, faster and more efficient slicing of food, for example. The scissors can be used for various items, such as for cutting meat, vegetables and other food products. The curved design of the scissor blades allows a user to easily operate the scissors to cut items disposed against a horizontal surface without having to uncomfortably and unsafely twist one's wrist as would be required with conventional straight-blade scissors. The scissors can have multiple blades, spaced apart a desired “bite-sized” length, to make cutting food products even faster. The hooked tip not only improves the slicing action by lifting the food ever so slightly during cutting but such hooked tips also have the additional advantage of grabbing food with a tong effect prior to slicing.

  • Patent number: 7926185
    Abstract: A pair of scissors with comb comprises a first blade having an edge, a second blade openably and closably supported together with the first blade and having an edge and a comb member attached to the first blade. The comb member is provided with a plurality of comb tooth groups with different characteristics from each other. The comb member is attached to and detached from the first blade. The mounting state of each comb tooth group is changed with respect to the first blade, whereby, for example, an extending direction of the comb tooth group is changed based on differences in the direction of eyebrows so that each comb tooth group can be used properly. Since an extending direction of a comb tooth of each comb tooth group inclines, the scissors with comb can be rendered convenient when eyebrows are trimmed.

    Abstract: A pair of gardening shears include a handle, a drive member, a control lever, a transmission device, and two cutting blades. The transmission device includes a housing, a pivot plate, a catch plate, a link, a catch flange, a restoring member. Thus, the restoring member is biased between the catch flange and the catch plate, so that the restoring member is not subjected to a pulling force to prevent the restoring member from being worn out by a pulling force during a long-term utilization. In addition, when the pivot head of the handle is rotatable relative to the housing, the stop post of the pivot head is movable to rest on the pivot plate to prevent the pivot plate from directly rubbing the inner wall of the pivot head.

  • Patent number: 4507864
    Abstract: Cutting shears or scissors have pivotally connected blades and shank portions extending at an acute angle with respect to the cutting edges of the blades wherein handles of the shears connected to the shank portions lie forward of the pivot connection between the blades in the direction of cut of material to be cut by the shears. The shears handles are configured such that the handle to be grasped by the fingers of the operator's hand is fixed to a blade which has a surface adapted for supporting the shears during use thereof. The other blade is provided with a handle particularly adapted for receiving the thumb wherein rotation of the thumb together with thrust of the forearm in the direction of cut or closing action yields a large mechanical advantage without substantial manual effort.
