A drop-spindle is a rod set in a whorl, used as a tool for winding fiber into thread by hand. It’s a period charge, found in the canting arms of von Spindlwerg, mid-16th C [NW 137]. Guillim, 1610 , also terms it a “wharrow-spindle” or “fuseau”, and assigns it to the canting arms of Trefusis.
The drop-spindle is shown with a load of thread by default; the fact is sometimes explicitly blazoned, e.g., a “threaded” or “full” drop-spindle. Empty drop-spindles are permitted, but must be so specified.
The period form of drop-spindle, with a small whorl and ellipsoidal load of thread (as in the illustration), is the preferred form for Society armory; the modern form, with a large disc-shaped or cone-shaped whorl and conical load, is no longer permitted.
