Demko Knives AD20.5 CPM-20CV Folding Knives

The Shark Lock is a unique mechanism operated by a tab on the spine of the handle that provides a secure, tactile engagement similar to the feel of a bolt-action rifle. It is designed to be finger-safe because the blade swings closed while your fingers remain clear of the cutting path. The lock tab also serves as a functional thumb ramp for better control during use.

This series offers two primary profiles: a 3.2 inch Clip Point and a 3 inch Shark Foot. The Clip Point is a versatile all-purpose shape, while the Shark Foot is a modified sheepsfoot design focused on utility and precision at the tip. Both blades feature a high flat grind designed for a balance of slicing performance and durability.

Yes, the AD20.5 is fully ambidextrous. The Shark Lock, dual thumb studs, and blade cutout are easily accessible from either side. While the pocket clip comes mounted for right-hand carry, each knife includes a secondary spare clip in the box specifically for the left side.

The AD20.5 20CV series includes options for textured G10 in blue or black, carbon fiber, and titanium handles in both smooth and textured finishes. Prices generally range from around $265 for G10 models up to around $390 for textured titanium versions. The titanium variants are especially popular for their slim profile and the distinct mechanical sound they make when locking open.

CPM-20CV is an excellent choice for those seeking a premium stainless steel with high edge retention and corrosion resistance. It allows the AD20.5 to stay sharp through heavy use while requiring very little maintenance compared to carbon steels.
