This Blade HQ Exclusive MG AD20S with a Slicer Shark blade is from Demko Knives. Features: Machine-ground stonewash Slicer Shark drop point blade made of CPM M4 steel.

Description: The Demko Knives MG AD20S is the next big thing in the EDC world, offering a top-quality folder at a fair price. It is like the AD20, but has a larger thumb hole and no thumb stud. It is as fun to fidget with as it is practically functional, which is largely thanks to the Shark Lock: a radical new system that provides solid lockup and can be trusted to keep your fingers safe. The lock is operated by pulling the fin back with your thumb or index finger-a motion similar to using a flipper opener. When the blade is locked open, the fin serves as a comfortable thumb ramp, which is jimped to increase your control over the knife. Additional jimping on the spine and a high grip option also contribute to the knife's usability. The MG AD20S hits the sweet spot that every EDC folder shoots for, and is likely to usurp that coveted spot in your pocket soon after dropping into your collection. Andrew Demko is a custom knife maker with an eye for innovation. He is the mastermind behind several of the strongest locking mechanisms to date, including Tri-Ad lock, the Shark Lock, the Scorpion Lock, and others. His knives are made to exacting standards, and are as functional as they are premium.
