As rugged as the U.S. Marines this knife is dedicated to. The SF stands for Semper-fi. The clip-point, German 4116 stainless steel blade is saber-ground and finished with a Tuff-Ex™ nonreflective coating. A deeply-checkered Kray-Ex™ handle delivers superior grip while encasing the knife’s extra-wide tang. The thick, steel butt cap doubles as a hammer. Sturdy steel guard provides protection with minimal interference when performing utility tasks. Includes an ambidextrous Secure-Ex™ sheath with a detachable belt loop. Blade length: 6-3/4". Overall length: 11-3/4". Weight: 12.3 oz.
