A weaver’s shuttle is a cloth-maker’s tool, containing a spool of the woof thread, which it carries back and forth between the warp threads strung in the loom. The default heraldic form can be more fully described as a “boat shuttle”; it was also blazoned in period armory as a “navette”. The shuttle is a period heraldic charge, found in arms granted in 1490 to the Worshipful Company of Weavers [Bromley & Child 263]. The shuttle is fesswise by default.
There is also a “stick shuttle”, a more primitive implement unique to Society heraldry; it is shown in two slightly different forms. (The first form was at one time misblazoned in the Society as a “weaver’s slea“, but that error has been corrected.)
For related charges, see drop-spindle, quill of yarn.
