Demo is one of the rarest SOG knives. In fact, the only original that is known to exist at present. The knife is 7.2 inches long straight and partially serrated blade is made from extra tough stainless steel AUS 8. This kind of steel offers less maintenance and greater edge holding ability. The steel is coated with Titanium Nitride and is considered to be the best coating that can be applied to steel. This is an amazing finish and is known to be scratch as well as peel resistant. The rubber handle of the knife provides a superior grip, sealing abilities with increased heat resistance and high traction.
