Use it to attach the Antic to a keychain or as a lanyard attachment. In addition, the ring also provides enhanced ergonomics. Slide your pinkie through the ring for a karambit-style grip. And while karambit knives are usually very aggressive self-defense tools, with the Antic, you can enjoy this knife style in a casual, pocket-friendly format. And unlike a strictly self-defense knife, the Antic offers other tools, too. The end of the ring is flat head screwdriver, which also doubles as a mini prybar. There's even a cleverly-placed bottle opener at the end of the back handle.
