Use of an anchor as a weapon is the stuff of Aeskellian legend. The song of how Captain Tief took up his ship's anchor to battle a fiend of Zhel is often one performed by Aeskellian tieflings. And upon hearing it, it gave one enterprising smith an idea.
Nowadays, war anchors are kept on most sailing ships. In the event that the usual anchor is sabotaged, war anchors are bound together and used as a replacement. But until then, they make excellent bludgeoning weapons.
