Cold Steel AD-15 Scorpion Lock Folding Knife

Revolutionary Locking System. Demko Innovation.

The Cold Steel AD-15 is one of the most innovative folding knives ever produced, combining the engineering brilliance of legendary knife designer Andrew Demko with Cold Steel's renowned manufacturing standards. Built around Demko's patented Scorpion Lock, the AD-15 offers exceptional strength, smooth one-handed operation and outstanding ergonomics, making it a premium choice for collectors, outdoor enthusiasts and those seeking a truly distinctive folding utility knife.

Its 3.5-inch spear point blade is precision crafted from premium American CPM S35VN stainless steel, delivering exceptional edge retention, toughness and corrosion resistance. The blade features a robust sabre grind, a practical false edge and strategically placed jimping along the spine, providing enhanced thumb purchase and precise control for detailed cutting tasks. Finished with a razor-sharp plain edge, it is designed to tackle demanding utility work with confidence.

What truly sets the AD-15 apart is its unique hybrid handle construction. Precision 3D-machined G-10 scales are mounted to robust steel liners, while the upper section—or yoke—is machined from a solid billet of 6061 aluminium. This integrated yoke incorporates a powerful compression spring that forms the heart of Andrew Demko's revolutionary Scorpion Lock. As the blade is opened using the ambidextrous thumb stud, the spring-loaded yoke securely engages the blade tang, creating an incredibly strong lock-up that is reinforced by the user's natural grip.

Designed for fully ambidextrous one-handed operation, the AD-15 offers intuitive opening and closing while maintaining exceptional safety and durability. Its innovative locking mechanism is engineered to resist heavy pressure and repeated use, giving users outstanding confidence during demanding outdoor, workshop and practical cutting tasks.

Combining groundbreaking engineering, premium American blade steel and exceptional build quality, the Cold Steel AD-15 Scorpion Lock Folding Knife stands as one of the most advanced and distinctive folding knives in the Cold Steel range.
