  • Patent number: 11148306
    Abstract: Hairdressing scissors include a pair of blade bodies each having a blade portion, a middle portion, and a handle portion in turn from a tip side. The handle portion includes first and second press-formed bodies each in the shape of a flat plate and facing each other along an axial center of a pivot to extend parallel to each other along a longitudinal direction of the blade body; and cylindrical collars and first and second resin materials configured to bridge the first and second press-formed bodies. The first press-formed body includes an extension portion extending toward an associated middle portion further than the second press-formed body to be connected to the associated middle portion, and the second press-formed body is spaced apart from the associated middle portion.
    Type: Grant

  • Patent number: 9718199
    Abstract: In opening and closing scissors, separation between both blades caused by inclination of one blade body relative to the other blade body is prevented or reduced. Specifically, with a head being in contact with a movable blade, a coil spring comes into contact with a head at one end and with the bottom of a counterbore at the other end. This pressing force allows a stationary blade to tightly abut on the movable blade. A taper face is formed at the stationary blade side of the head to press and expand the one end of the coil spring radially outside a pivot.
