The Cold Steel AD-15 is a high performance production version of Andrew Demko’s innovative AD-15 folder. The AD-15 introduced the innovative Scorpion Lock, which provides secure blade lock-up with a pull-back lever along the spine. Andrew modified a traditional lockback design by integrating it into the handle and adding a stop pin, eliminating blade play and overtravel issues.

The saber ground spear point blade comes with a false edge and includes jimping on the spine to assure great piercing ability and edge control when precision cutting is required. The AD-15’s unique hybrid handle is what distinguishes it the most; because it features Andrew’s famous Scorpion Lock. The bottom portion of the handle has 3D-machined G-10 scales mated to steel liners, while the upper portion of the handle, called the “yoke” is crafted from a 3D-machined 6061 aluminum billet that includes an integral back spacer which conceals a strong compression spring. To open the knife, simply engage the thumb stud and watch the yoke rise up, until it falls snugly into a deep notch cut in the blade’s tang. Held securely by constant pressure from the spring and, supported by the strength of one’s grip, the Scorpion Lock is incredibly secure.
