A trowel is a small handheld tool used by masons (and later by gardeners), for spreading, scooping, or smoothing. It’s a period charge, found in the arms of the Worshipful Company of Plaisterers, 1545 [Bromley & Child 201]. The trowel has its handle to base by Society default, with the blade flat-on to the viewer. For related charges, see hoe, spade.
