Andrew Demko’s innovation in the custom knife world includes several unique and incredibly strong locking mechanisms for folders. The Shark Lock, included on the American-made MG AD20S TAD Edition, is his latest design. This self-adjusting lockback mechanism features a stop pin that re-distributes the load of vertical positive and negative pressures on the lock and transfers it into the handle frame where it can be more effectively absorbed. The Shark lock, unlike most lockbacks, is easy to deploy and not hindered in any way. The knife opens and closes as fast as a frame lock on bearings. The Shark lock requires little effort to disengage; just pull back on the natural ramp and swing the blade closed.

The MG AD20S TAD Edition is a stout knife built to handle most any task. This “Slim” edition has a thinner Magnacut blade and full flat grind for incredibly aggressive cutting power. While thinner than his standard blade, this TAD Edition is still up for heavy duty work. The ergonomic and robust titanium handle gives the knife a secure feel in the hand. The stainless steel spring pocket clip is set up for tip-up, right-hand carry.

Build quality and innovative design are the hallmark of this Demko MG AD20S TAD Edition. These knives are made to exacting standards and are as unique as they are durable. Our TAD Edition comes with our signature multi layer topo pattern laser applied on the slabs and our logo at the base of the blade.
