The Demko Knives AD20.5 is the next big thing in the EDC world, offering a top-quality folder at a fair price. 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 is ambidextrous, 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 AD20.5 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.
