ABSTRACT:
An improved scissors includes a pivot joint having a pivot axis, a first blade member having a first cutting edge and a longitudinal axis, and a second blade member having a second cutting edge. The second blade member is pivotally coupled by the pivot joint to the first blade member with the first cutting edge adjacent and in contact with the second cutting edge. Moreover, the pivot joint is coupled to the first blade member to incline the first blade member relative to the second blade member and the pivot joint, so that the inclination of the first blade member produces a load transverse to the pivot axis of the pivot joint, which corresponds to the direction along the longitudinal axis of the first blade member to produce and determine the tension and friction along the cutting edges. Further, the first blade member may also include a first ride area, and the second blade member may also include a second ride area, so that the first ride area is spaced from and free of contact with the second ride area. Therefore, the scissors may be substantially free of any friction or drag at the "ride" area.
