The Heretic Knives Nyx V2 Prototype is an out-the-front (OTF) automatic knife with a double-edge blade. The blade has a highly polished cracked ice finish, and it sits in a lightweight aluminum chassis that's easy to carry every day. The OTF mechanism fires and retracts the blade quickly and the same way every time. Heretic Knives builds it in the USA, so the fit and finish are what you'd expect from them. Since it's a prototype, it's made in limited numbers, which suits collectors who want something unusual and people who plan to carry and use it.
