When blade length is restricted, performance shouldn’t be. The Full Immunity™ delivers elite cutting power in a compact, concealment-friendly design built for serious everyday carry.

The Benchmade 290BK-2 Full Immunity™ is engineered for environments where blade length matters — but performance still counts. Designed for compact concealment and fast deployment, this premium sub-2.5” folding knife delivers exceptional strength, edge retention, and utility in a streamlined package.

At its core is a 2.49” CPM-M4 high speed steel Wharncliffe blade (62-64HRC), finished in durable Cobalt Black Cerakote® for enhanced corrosion resistance and low-visibility performance. The Wharncliffe profile tapers to an ultra-fine point, offering precise control for detailed cutting tasks and everyday utility work.

The Woodland Green 6061-T6 anodized aluminum handle provides strength without excess weight, keeping total carry weight at just 2.29 oz. Benchmade’s trusted AXIS® Lock ensures ambidextrous, secure operation, while the included lanyard allows fast pocket retrieval and manual deployment when seconds matter.

Compact, capable, and refined — the Full Immunity™ is concentrated utility in a legally mindful configuration.
