A jimped / ridged thumb rest on the back of the zinc-alloy blade holder provides a comfortable way to add extra force for cutting through denser materials. for convenience a single SK-5 hardened carbon steel blade is included to get you started with additional replacement blades available at most hardware stores. The comfortable and ergonomic, Estwing blue and yellow handle is made from high-visibility polypropylene and TPR rubber that is weather resistant. The lock back mechanism on the spine keeps the blade securely open when in use and prevents accidental closure and injury.
