This is a special little everyday carry folding knife for work. This one features an aluminum handle, 440 stainless blade, fully serrated with gut hook, seat belt cutter and glass breaker. A really handy little tool and very helpful to have with you in cases of emergency or for your daily work tasks. The hook blade / serrated saw-like blade combination tears and saws its way through cardboard boxes very easily. This is a really unique little rescue saw/knife to own for your collection. It's one of those “must own” tools to take with you in the car or to throw in your bug out bag or purse.
