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

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