A needle is a slender sliver of metal or bone, sharpened at the end and used for manipulating thread. In Society armory, the default needle is the “sewing needle” (often so blazoned): a metal needle with a hole in one end for thread, used for hand sewing. It’s a period charge, found in the canting arms (from dial. Italian gugela) of de Agugellis, mid-15th C. [Triv 41]. Sewing needles are sometimes found threaded; their points are to base by Society default.
There is also the “knitting needle”, which should be double-pointed; one of the earliest representations of knitting, the Buxtehude altarpiece c.1395 [Richard Rutt, A History of Hand Knitting, p.49], shows needles in this form. Although a period artifact, the knitting needle is unattested in medieval armory. It doesn’t seem to have a default orientation in Society blazonry; the illustration shows a double-pointed knitting needle palewise.
