In Willie and Modesty's fights there is a great emphasis on unarmed combat and unusual weapons. Modesty's weapon of choice is a "kongo" or yawara stick and as for firearms she begins by preferring the Colt .32 revolver and Mab Brevete .32 ACP auto pistol, although in later books she switches to carrying a Star PD .45 auto pistol. Willie's preferred weapon is the throwing knife, of which he usually carries two. Many other strange weapons (such as the quarterstaff, épée, blowgun, and sling) and unexpected fighting techniques are also featured.
