The Demko Knives AD20s is the definition of a hard-use folder. Designed by Andrew Demko, creator of the iconic "Tri-Ad" lock used by Cold Steel, the AD20s is an evolution of the AD10 and features Andrew's new and menacing Shark lock.
Like the Scorpion and Tri-Ad lock, the Shark lock is a patented design where speed is not hindered in any way, and the knife opens and closes as fast as a frame lock on bearings. In addition, it offers comparable lock strength to the Tri-Ad design, while being able to be deployed with a flick of your wrist.
Built for heavy-duty use, the AD20s features a razor-sharp 3.5" D2 tool steel blade. Hollow-ground for exceptional sharpness, the AD20s cuts like a demon and can withstand any heavy use thrown it's way.
The lightweight Grivory (high-performance polymer) handles are incredibly robust, durable, and resistant to the elements. In addition, this unique blade features a stop pin that re-distributes the load of vertical positive and negative pressures on the lock, meaning the stop pin receives all positive pressure (pressure on the cutting edge) and transfers it into the handle frame and liners where it can be more effectively absorbed – ensuring secure lock up at all times.
If there's ever a knife that inspires confidence in hand, it's the rock-solid Demko Knives AD20s. Overbuilt and over-engineered, this beast of a blade is the perfect heavy-duty everyday folder that will serve you unfailingly through all of life's adventures and escapades.
