Staying true to Cold Steel's legacy of producing the most robust and secure folding knives, they conducted extensive tests comparing the Atlas lock to their renowned Tri-Ad lock. Through rigorous torture tests, the Atlas lock demonstrated superior shock resistance and weight-bearing capacity. When it comes to using a folding knife, quick deployment and safe retraction are paramount. The ambidextrous slide lock allows for swift one-handed operation, keeping your fingers clear of the blade's path. Experience the difference with the Atlas lock in your hand.
