Pinking shears

[1][2] In 1874, Eliza P. Welch patented an improved design for a pinking iron, which featured a pair of handles.

[5] In 1934, Samuel Briskman patented a pinking shear design (Felix Wyner and Edward Schulz are listed as the inventors).

[6] In 1952, Benjamin Luscalzo was granted a patent for pinking shears that would keep the blades aligned to prevent wear.

[8] These scissors can also be used for decorative cuts and a number of patterns (arches, sawtooth of different aspect ratios, or asymmetric teeth) are available.

The verb "pink" dates back to 1300 meaning "pierce, stab, make holes in".
