AD20S vs. Shark-Cub: Which Demko Knife is Right for You?
- Article written by Corey Decker - TREAD Magazine
Demko Knives, known for its innovative folding knife locks, offers two standout models: the AD20S and the Shark-Cub. Both knives utilize the Shark-Lock mechanism, which enhances both functionality and ease of use. However, these two models serve different purposes, with distinct features and materials that cater to varying user needs.
Shark-Lock Mechanism: A Core Innovation
Both the AD20S and the Shark-Cub use the Shark-Lock, a spine-mounted locking mechanism. This design allows the blade to open and close efficiently with one hand, reducing the need for excessive wrist manipulation. The Shark-Lock mechanism distributes load across a pin that connects the blade tang with the handle. This structure helps in absorbing pressure effectively, similar to the Tri-Ad lock, another Demko creation that has been used in Cold Steel knives. The Shark-Lock’s placement on the spine prevents dirt from interfering with its operation, which makes it reliable in various conditions. With this lock, users can flick the blade open with ease while ensuring it stays secure during use.
AD20S: A Heavy-Duty Tool
The AD20S features a clip-point V2 blade with a sharpening choil, thumb ramp jimping, and a reinforced tip. The G10 handle houses titanium liners that support the Shark-Lock mechanism. This knife includes dual thumb studs for multiple opening options and a right-hand, tip-up stainless steel pocket clip. The AD20S runs on caged bearings that provide smooth operation. This knife uses premium steels like CPM 20CV or CPM 3V, designed for tasks requiring edge retention and toughness.
Shark-Cub: Designed for Everyday Use
The Shark-Cub is a smaller, more budget-conscious model with a Shark Foot blade. It uses AUS10A steel, which provides a balance of hardness and corrosion resistance. The handle is made from glass-reinforced nylon (GRN), a lightweight thermoplastic with high durability. This knife includes a deep-carry, ambidextrous pocket clip, enhancing everyday usability without limiting carry options. Its caged bearing system ensures smooth deployment, similar to the AD20S.
