$ 325

When blade length is restricted, necessity isn’t. Designed for ease of concealment and compact utility, the Auto Immunity™ features a sub-2.5-inch CPM-M4 blade with a Cobalt Black Cerakote finish, boasting outstanding edge retention and strength in a Wharncliffe profile tapering to an ultra-fine point. The included lanyard speeds up retrieval from the pocket for quick deployment via the ambidextrous Auto AXIS mechanism, enabling rapid response in evolving situations. Finished with anodized Woodland Green aluminum handle scales, the Auto Immunity™ is a concentrated dose of full-fledged utility in a compact configuration.
