The Benchmade Full Immunity is a compact tactical folding knife engineered for everyday carry and concealed use. Its sub-2.5-inch wharncliffe blade is crafted from CPM-M4 powder-metal high-speed tool steel hardened to 62–64 HRC, delivering exceptional edge retention, wear resistance, and toughness. The straight edge and acute tip geometry of the wharncliffe profile makes it well-suited for precise cutting tasks.

The handle is machined from 6061-T6 anodized aluminum, offering a lightweight yet durable grip that resists corrosion and can be milled with fine detail. The knife operates on Benchmade's renowned AXIS lock mechanism, providing secure, reliable lockup with smooth manual deployment. A reversible pocket clip allows for flexible carry configurations.

Benchmade manufactures every Full Immunity at their facility in Oregon City, Oregon, and backs it with a lifetime warranty. All knives are eligible for Benchmade's LifeSharp service, which includes free re-sharpening, cleaning, oiling, and adjustments for the life of the knife. Available in multiple handle colorways including Flat Dark Earth, Woodland Green, and Crater Blue.
