The handle is long, making the knife in length when opened. The blade steel is Crucible's 154CM and is thick. The butt-end of the knife is square-shaped and has a hole for tying a lanyard. Some models are made with partially serrated blades to aid in the cutting of seatbelts or webbing. The handle of the SARK is made of two titanium liners utilizing a Walker linerlock and a double detent as the locking mechanism. Titanium is used due to its exceptional strength-to-weight ratio and corrosion resistance. The handle's scales are made from black G-10 fiberglass, although models were made for a few years using green G-10. A pocket clip held in place by three screws allows the knife to be clipped to a pocket, web-gear or MOLLE. Each model is equipped with Emerson's Wave opening mechanism, a small hook on the spine of the blade designed to catch the edge of a user's pocket, opening the blade as the knife is drawn.
