Cold Steel AD-15 might be the most comfortable and user-friendly folder. Modeled after Andrew Demko’s patented original, it offers ambidextrous operation and opens and closes with a single hand. The satin finish saber ground spear point blade comes with a false edge and includes jimping on the spine to ensure great piercing ability and edge control when precision cutting is needed. The AD-15’s unique hybrid handle is what distinguishes it the most; because it features Andrew’s famous Scorpion Lock. Its bottom portion of the handle has 3D-machined black 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 backspacer 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 never disappoints you!
