The product of collaboration between Gerber and survival expert Bear Grylls, the Folding Sheath Knife is a compact knife that folds for easy storage and portability. A dual-sided thumb stud makes for easy one-handed opening. Its half-serrated, high-carbon stainless steel blade is ideal for edge retention and cutting rope, and it comes with a nylon sheath. A rubber grip and the lockback feature provide extra safety.
