This Custom Prototype is a new design from Marfione Customs. It features a stainless steel handle with carboquartz inlays and blue anodized hardware. The blade is a mirror polished Bohler M390 stainless steel dagger. The thumb slide is on the top, as opposed to the side, like other Microtech knives. The pocket clip has "Prototype" engraved on it. This OTF is truly a magnificent piece, and one that you will want to add to your collection.
