The “claymore” (Scots Gaelic claidheamh mór) is the traditional great sword of Scotland. In the Society, the claymore is drawn as the actual 16th C. artifact [Stone 181], with angled quillons terminating in trefoils. The modern heraldic stylization, with a basket hilt [Parker 566], is a post-period form.
Duncan MacGregor bears: Gules, a cross and overall in saltire two claymores inverted, all conjoined Or.
Deaton Claymore bears: Vert, two claymores in saltire surmounted by a third inverted proper, enfiling a ducal coronet Or.
