The Benchmade 556 Mini-Griptilian Exclusive Prototype is an extremely rare production piece.  It is the Prototype for our 500 piece Exclusive run of the Benchmade 556 with M4 blade with only a few Protos in existence. Features are the same as the production run, but the blade is marked "Prototype" on the backside rather than being individually serialized.  This knife is in brand new condition with original box, paperwork and microfiber bag.   

The Blade: Features a high-speed CPM-M4 powder steel blade with gray Cerakote finish. The modified drop point style blade is crafted from wear resistant CPM-M4 powder steel and given a Cerakote coating for ultimate protection. Marked "Prototype" on backside of blade.

The Handle: Familiar textured Valox durable handle houses the industry leading Axis lock for bank-vault lockup. A tip-up reversible black pocket clip makes for true ambidextrous carry.
