BM2900BK: 2900BK Auto Immunity | Benchmade Design

Benchmade Knives

Swift, nimble, and powerful, the Benchmade Auto Immunity is one incredible knife. Taking inspiration from other Benchmade models, the Immunity features textured aluminum handles, an AXIS lock that double as the automatic opening mechanism, and a wicked sharp Wharncliffe blade. Although all of the aforementioned characteristics are more than enough reason to love this blade already, the extremely ergonomic handle elevates the Immunity to another level, further cementing Benchmade as one of the big dogs of the production knife industry.
