Cold Steel AD-15 Scorpion Lock 58SQODBK OD Green Black pocket knife, Andrew Demko design

The Cold Steel AD-15 Black is a large and robust pocket knife with a black blade and black handle. Designed by Andrew Demko. This American designer is responsible for a large part of Cold Steel's folding knife successes. The AD-15 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 as a scorpion's tail hangs over his own body, the lockbar bends from the spine of the handle down to the blade.
