Derived from the original Gerber Hinderer comes the Hinderer 22-01870 CLS, deemed the Life Saver. Ther Gerber Hinderer CLS has an oversized thumbstud to open the 440A stainless steel partially serrated blade. The blade can be folded back into the knife by activating the patended liner lock system. To keep a low profile and for tactical reasons a black non-reflective coating has been added to the Hinderer CLS. On the opposite end of the knife is a fold-out seatbelt cutter and a rigid window punch Built into the handle is an oxygen tank wrench.
