With only two fingers, you can hit with a force to break any bones. Our Bone Crusher is small but packs a powerful pouch when it comes to defense. It features a mini design which makes it easy to conceal and carry (do not take it through airport security). It offers two large holes for your index and middle finger while the bottom t-shape provides a supporting stop in the palm of your hand. The head sports a 4 spiked edge while the body offers three holes for extreme design. It also features a spotted blue over black finish. Length: 3 inch, Width: 2.25 inch
