Understanding the Cold Steel Andrew Demko AD-15

The Cold Steel Andrew Demko AD-15 is defined by its revolutionary Scorpion Lock which uses the strength of your own grip to reinforce the blade's security. This series offers a variety of finishes and materials that cater to both premium collectors and heavy-duty users.

How does the Scorpion Lock on the AD-15 work?
The Scorpion Lock utilizes a yoke that runs along the top of the handle and hooks over a pin on the blade tang to lock it in place. Because your hand grips over the lock bar during use, the pressure of your own grip actually strengthens the lock-up while you work. You can learn more about this system in our guide to folding knife lock types.
What blade steels are used in the AD-15 series?
The AD-15 series typically features S35VN stainless steel for premium edge retention and toughness. For those seeking a more budget-friendly option, the AD-15 Lite models utilize Japanese AUS-10A steel paired with Griv-Ex handles to maintain high performance at a lower price range.
Is the AD-15 suitable for left-handed carry?
The AD-15 is a fully ambidextrous knife designed for both left and right-handed users. It features a two-position pocket clip that can be mounted on either side and a centrally located lock bar that is easily operated by either hand.
Can the AD-15 be used while wearing gloves?
The AD-15 is an excellent choice for use with gloves due to its generous handle size and accessible lock mechanism. The ergonomics were specifically designed to provide a secure grip and easy deployment even when your hands are protected by heavy-duty work gloves.
How do you close the AD-15 safely?
To close the AD-15, you simply lift the locking yoke away from the handle to disengage the blade. This movement allows the blade to swing closed in a finger-safe manner, as your hand remains on the outside of the handle and away from the cutting path.
