Joseph Bowden’s Micro Hatchet condenses its namesake into a piece of functional jewelry that can be worn around the neck, even when it’s not hacking away. A large center hole allows for different grip retention and positions. The Inuit style blade is capable of cutting through bones, according to the website, though why you’d want to do that for any reason other than dressing game is something we don’t want to know.
If you do plan to wear this around your neck as the site suggests, make sure you know the rules of wherever you’re going. Don’t want to end up facedown with your hands cuffed behind your back. You never know how people might react.
