The dual action is a favorite among both women and men. This recurved blade is made from stainless steel with a two-tone finish. The grip is zinc alloy that is contoured for a comfort. There are sand paper inserts for working in wet conditions which is an added bonus. A glass breaker is featured at the end of the handle with a steel pocket clip. Also included is a quick release nylon sheath. This type of knife is great for Police Officers, Emergency personnel, and Fire Fighters. Sometimes you just have one free hand and this baby gets the job done in a few quick motions. If an accident occurs you can break glass and cut a seatbelt off all with one hand. EMTs can hold an IV drip and cut a pants leg off. This knife is capable of that and so much more.
