The Demko AD20.5 delivers the revolutionary Shark Lock in a lightweight, EDC-friendly package—all at a surprisingly accessible price. Designed as a scaled-down version of the iconic MG AD20, this knife retains all the tactical precision and smooth action while improving portability and usability for everyday carry.
 
At the heart of the AD20.5 is the Shark Lock mechanism, positioned along the spine and operated with a ramp-like ‘fin’ that allows for lightning-fast deployment and effortless one-handed closing. This unique locking system not only enhances strength and safety but also acts as a blade launcher—engaging the AUS-10A steel blade with a simple flick of the wrist.
 
Available in both Clip Point and Shark Foot (Sheepsfoot) variations, the AD20.5 is a tough, reliable performer. With a DLC-coated blade for added durability and corrosion resistance, textured Grivory handles for a secure grip, and a fully ambidextrous pocket clip, this knife is ready for hard work, self-defense, or everyday cutting tasks.
