A float, or flote, is a bowyer’s tool, a multi-bladed wood shave used to shape the bow. It’s a period charge, used as a badge by Oldhalle, 1457 [Hope2 182], and in the arms of the Worshipful Company of Bowyers, 1488 [Bromley & Child 25]. The float has its handle to chief by default. See also plane.
Domhnall Ó Catháin bears: Per pale azure and sable, a griffin segreant and on a chief dovetailed argent two floats gules.
