When blade length is restricted, necessity isn’t. The Benchmade 290BK-1 Full Immunity™ delivers full-strength everyday carry performance in a compact, concealment-friendly platform built for real-world utility. At ClassicBlades, we focus on premium knives that carry small but work big—and this one is exactly that.
Designed for compact utility and fast access, the Full Immunity™ features a sub-2.5" CPM-M4 high-speed tool steel Wharncliffe blade with a tough Cobalt Black Cerakote® finish for added wear protection. The Wharncliffe profile tapers to an ultra-fine point for precise cuts, controlled slicing, and detail work.
Finished with Flat Dark Earth (Burnt Bronze) 6061-T6 anodized aluminum handle scales, a proven AXIS® Lock, and a reversible mini deep-carry pocket clip, this is a concentrated dose of full-fledged Benchmade utility in a compact configuration. The included lanyard speeds up retrieval for quick manual deployment when things move fast.
