Low friction pivot assembly for scissors
A low-friction hub assembly for pivotally connecting a pair of scissors or lever-like members employs a pair of cooperative hub members. A first hub member has an exterior threaded surface which threadably engages with an interior threaded surface of the second hub member. Each of the hub members has annular shoulders which engage against opposed annular surfaces of surrounding aligned pivot openings of the scissors. A locking member comprising a pair of opposed pawls engages a serrated surface to lock the subassembly. A throughbore extends through the pivot assembly.
Hair cutting scissors
A pair of scissors has two shears movably mounted to pivot about an axis, each of the shears having a blade (3) extended by a shank (4, 5). The first shank (4) is covered by a grip in the form of an elongate body that is provided with a lateral opening (8) and that is suitable for being inserted transversely between two fingers of a hand to a position where it bears against the crook where the two fingers meet. The second shank (5) is terminated by a half-ring forming a cradle (10) for receiving the thumb. The first shank (4) is a bent shank. The lateral opening (8) in the elastically deformable grip extends into the inside of the grip forming a sheath into which the first shank (4) can be inserted in adjustable manner by slidable movement. The end of the cradle (10) that is closer to the first shank (4) is bent towards the inside of the cradle to form an abutment (11) for retaining the thumb.

Training scissors
A pair of training scissors structurally configured to help a child learn proper finger positions for use of scissors. The handles include solid bowl apertures to positioned so that the tips of the fingers are desirably positioned so that the tips of the fingers are utilized to operate the scissors. The scissors also include an illumination feature that encourages a child to practice opening and closing the scissors as they are motivated by the light. This repetition serves to reinforce the proper finger positions, and the repetitions also help develop muscle strength.

Slide cutting shears
A pair of slide cutting shears that have identical cutting angles of approximately 53 degrees on the thumb and finger blades, and where the thumb blade has approximately only 40% of the top end of the blade sharpened and the remaining section of the working blade is radiused and cannot cut. The shears have a four finger grip, and adjustable bump stop and a tightenable pivot pin assembly to draw the blades closer.

Pull-type cutters
One feature pertains to cutters that include a first lever, a second lever having a bottom edge, and a cutting lever having a top edge. A first member rotatably couples the first lever to the second lever, a second member couples the cutting lever to the first lever and/or the second lever, where the second member provides a pivot for the cutting lever to rotate relative to the second lever. A means for rotating the cutting lever relative to the second lever to move the top edge toward or away from the bottom edge when the first lever's first end is moved relative to the second lever's first end is provided, where the first lever, the second lever, and the cutting lever are arranged in a side-by-side configuration such that each has a longitudinal axis that is parallel to each other when the cutters are in a closed position.

HAIRDRESSING SCISSORS
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.
