The Shark-Lock™ mechanism is situated on the spine of the knife and operated with a ramp-like ‘fin.’ Opening the blade makes the spring-driven lock arm move up and then into a notch in the tang, situating it beneath a lock pin. This range of movement is noteworthy. It’s unique in that the locking mechanism moves forward and back while also moving up and down. This allows for a greater sized blade tang, making a better mechanical advantage in a specific area. And because the drive spring that moves the locking element up into the locked position is contained within the locking arm itself, it won’t be subject to dirt and grime. The Shark-Lock™ is very comparable to most Tri-Ad locks for its size and weight. The AD-20.5 has been tested to 875-inch pounds of torque, this is a very impressive number for a 3.5 oz. knife.

    “The pair”

    Quick delivery, I am a big fan of the Demko 20.5 it’s a great tool. I bought a dlc from a different company but had seen the blacked out ones had to own them. I haven’t used them yet but the action is smooth on both shark foot and clip point. I did check the action on both and they work just as smooth as the other ones I own. I highly recommend buying from REC fast process from order to delivery and updates in between. Thank you guys and your team!
