The best just got an upgrade! The former MK2 from Microtech Knives is now the Delta Frag, which features a textured aluminum handle for improved grip and a ported chassis to expel dirt and debris which is common in an OTF that is part of an EDC rotation. The DLC coated blade is fluted to allow for easy cleaning out. The internals are Nickel Boron coated for extra corrosion resistance. The Microtech Ultratech is the first ever OTF (out the front) knife produced by Microtech Knives. It features a 3.4"  blade with black finish. The Ultratech features a 5" black anodized 6061-T6 aluminum handle with bead blast finished pocket clip, glass breaker and stainless steel hardware. Double action thumb slide is located on the side of the handle for out the front deployment and retraction.
