Pinking Wood Ranger shears (http://www.career4.co.kr/bbs/board.php?bo_table=ci_consulting&wr_id=59148) are scissors with noticed-toothed blades instead of straight blades. They produce a zigzag pattern as a substitute of a straight edge. Before pinking scissors have been invented, a pinking punch or pinking iron was used to punch out a decorative hem on a garment. The punch would be hammered by a mallet towards a tough surface, and the punch would lower by the fabric. In 1874, Eliza P. Welch patented an improved pinking iron design, that includes a pair of handles. In 1934, Samuel Briskman patented a pinking shear design (Felix Wyner and Edward Schulz are listed as the inventors). In 1952, Benjamin Luscalzo was granted a patent for pinking shears to maintain the blades aligned to forestall put on. Pinking shears are used for reducing woven cloth. Unfinished cloth edges will easily fray, the weave turning into undone, and threads pulling out simply. The sawtooth pattern does not prevent the fraying however limits the length of the frayed thread and thus minimizes injury. These scissors will also be used for decorative cuts, and a number of other patterns (arches, sawtooth of different side ratios, or asymmetric teeth) can be found. The cut produced by pinking shears could have been derived from the pink garden plant, in the genus Dianthus (the carnations). Patent Office, United States (1874).
