Pinking shears


Pinking shears are scissors, the blades of which are sawtoothed instead of straight. They leave a zigzag pattern instead of a straight edge.
The pinking shears design was patented by Louise Austin in 1893. In 1934, Samuel Briskman patented a pinking shear design. In 1952, Benjamin Luscalzo was granted a patent for pinking shears that would keep the blades aligned to prevent wear.
Pinking shears have a utilitarian function for cutting woven cloth. Cloth edges that are unfinished will easily fray, the weave becoming undone and threads pulling out easily. The sawtooth pattern does not prevent the fraying but limits the length of the frayed thread and thus minimizes damage.
These scissors can also be used for decorative cuts and a number of patterns are available. True dressmaker's pinking shears, however, should not be used for paper decoration because paper dulls the cutting edge.

Etymology

The cut produced by pinking shears may have been derived from the plant called a pink, a flowering plant in the genus Dianthus. The color pink may have been named after these flowers, although the origins of the name are not definitively known. As the carnation has scalloped, or "pinked", edges to its petals, pinking shears can be thought to produce an edge similar to the flower.
The word "pink" can be used as a verb dating back to 1300 meaning "pierce, stab, make holes in".
