Abstract
An improved pair of scissors having two blades pivotally connected by a swivel pin, the blades having their respective cutting edges which engage with each other at a point immediately adjacent to the swivel point when the cutting edges are in the closed position. This construction eliminates the possibility of creating the so-called "dead space" thus enabling opening of the cutting edges wide and providing a constant cutting length as well as a distinct sharpness.
Claims6
A pair of scissors, comprising:
- at least two elongated blades each having a cutting edge and a loop handle;
- and
- a swivel pin connecting the blades to provide for pivotal movement thereof with respect to each other;
- the cutting edges of both blades falling substantially in line with said swivel pin and slightly crossing each other adjacent their terminal ends when said elongated blades are brought into a closed state, the outer peripheral portion of the swivel pin serving as a stopper when the blades are opened to a degree at which the normal cutting operation begins.
