Built for serious users, this folding knife features a robust G10 handle with copper foil accents for enhanced grip and aesthetics. The ceramic ball bearing mechanism ensures smooth, consistent deployment, while the rack lock provides secure blade retention during use. The reversible stainless steel pocket clip accommodates both left and right-handed carry preferences. Measuring 7.87 inches open and 4.49 inches closed, the Badger balances portability with capability. Its 3.38-inch Wharncliffe blade excels at slicing and detail work. Hardened to 59-61 HRC, the blade maintains optimal performance without sacrificing maintainability. At just 129 grams, it won't burden your EDC loadout. Perfect for outdoor enthusiasts, campers, and professionals who demand a knife that performs consistently and stays sharp with minimal fuss.
