This keychain combines a useful kubaton and a monkey fist. The design fits nicely in hands of all sizes and is made from purpleheart, which is a very hard wood. The inlayed design is made from epoxy which helps strength the entire structure. As with any tool for self-defense, this is not intended to be misused, only for defense. It is coated in polyurethane to protect it from the elements. 5 inches long, ¼” inch thick, maximum width 1”. Paracord braid is about 7 inches long. The monkey fist contains a 1” steel chrome ball.
