Pinking Shears

A Zigzag Edge That Limits Fraying

Woven cloth is a grid of threads, and a straight cut across that grid leaves every thread end free at the same line. Wear, handling and washing pull those ends loose, the weave becomes undone, and threads pull out easily — the familiar frayed edge. Pinking changes the geometry of the problem. Because the blades are sawtooth, the cut edge runs in a zigzag, so no single line of thread ends is exposed at once, and any thread that begins to work loose can only fray back to the next tooth of the pattern. The sawtooth does not prevent fraying altogether, but it limits the length of the frayed thread and thus limits the damage, buying the edge time and stability. That makes pinking a quick, practical edge finish for seams and samples where a folded hem or overlocked finish is not needed, and it is one reason pinking shears are valued for cutting fabric swatches, whose edges must stay neat through repeated handling.

The same blades serve decoration as readily as utility. Pinking shears can be used for decorative cuts, and there are a number of patterns beyond the standard zigzag: arches, saw-tooth of different aspect ratios, or asymmetric teeth. Changing the tooth changes both the look of the edge and its behavior — a finer tooth gives a subtler finish on light cloth, while a bolder tooth makes a deliberate scalloped or peaked effect on craft and dress fabrics. The tool itself demands more force than ordinary scissors, because two toothed blades must mesh cleanly along their whole length, and a well-made pair is judged by how evenly those teeth meet: gaps leave uncut threads, while a clean mesh shears the zigzag in one pass.

How Shears Named a Flower and a Color

Few sewing tools have left a mark on the language as surprising as this one. The cut produced by pinking shears has given its name to pinks: hardy carnations of the Dianthus genus, named for their petals' pinked edges, whose frilled, notched petal margins look as though they have been cut with toothed blades. The color pink was then named after these flowers. The chain runs from tailor's tool to flower to color word, so every use of the color name quietly recalls a zigzag cut edge in cloth. To pink, as a verb for making a notched or perforated edge, is older than the shears' modern form, and the flower's name preserves that cutting sense in everyday speech.

In the sewing room, the shears sit among the edge finishes a maker chooses between for each fabric and purpose. A hem encloses the raw edge completely; a binding wraps it; an overlocked stitch sews over it; pinking trims it into a self-limiting zigzag with a single cut and no extra material or stitching. For swatch books, sample cards and internal seam allowances, that speed and simplicity are exactly what is wanted. Used with an understanding of their limit — they slow fraying rather than stop it — pinking shears remain the fastest complete answer to the raw edge problem that woven cloth presents on every cut.
