Cold Steel AD-15 Black 58SQB pocket knife, Andrew Demko design

The Cold Steel AD-15 is a large and robust pocket knife, designed by Andrew Demko. This American designer is responsible for a large part of Cold Steel's folding knife successes. This AD15 is another masterpiece. One of Demko's most famous inventions is the Tri-Ad-lock. A rock-solid lock which is tested often as the strongest on the market. This production version of Demko's custom AD-15 introduces a new lockings mechanism: the Scorpion Lock. Just as a scorpion's tail hangs over his own body, that is how the lockbar bends from the spine of the handle down to the blade.
