The BLACKHAWK! UK-SFK or United Kingdom Special Forces Knife was designed specifically for Britain’s elite Special Forces. Based upon their stringent specifications, BLACKHAWK! design team drew from the groundbreaking works of Col. Rex Applegate, W.E. Fairbairn, and Brent Beshara to create the ultimate combat dagger. The UK-SFK’s broad, symmetrical blade is precision ground from premium D-2 tool steel for an exceptional combination of edge geometry, point strength, and penetration. Its integral crossguard and distinctive full-tang handle design are borrowed from Brent Beshara’s XSF-1 dagger for outstanding strength and ergonomics. The UK-SFK comes complete with an injection-molded nylon sheath specially designed to support vertical and horizontal wear on MOLLE gear and attachment to BLACKHAWK!’s drop leg holster platforms.
