Infidel® Family: The Gold Standard of Tactical Automatics

The Infidel® Family represents Benchmade’s most iconic expression of tactical automatic design. Built around a perfectly symmetrical out-the-front platform, Infidel® is engineered for reliability, balance, and decisive deployment when it matters most. Its double-action OTF mechanism delivers fast, controlled extension and retraction, while the ambidextrous design ensures consistent performance from either hand. Purpose-built for duty use, this tactical automatic knife delivers precision, confidence, and unmistakable presence.

Symmetry, Speed, and Duty-Ready Design

Every Infidel® is built with a face-mounted deployment system and a fully symmetrical profile, allowing intuitive, ambidextrous operation in high-pressure environments. The dagger-style blade delivers strong piercing capability and controlled penetration, while the robust aluminum handle provides a secure grip even with gloves. Designed to integrate seamlessly into professional loadouts, Infidel® knives feature MOLLE-compatible carry options and construction trusted by military and law-enforcement users worldwide.

Within the lineup, the Infidel® Black Aluminum stands as the original tactical powerhouse, offering full-size reach, a commanding grip, and uncompromising performance for duty-focused applications. For those who prefer a more compact profile, the Mini Infidel® Black Aluminum delivers the same fast, double-action OTF reliability in a smaller format, making it easier to carry discreetly while remaining instantly ready when deployed.
