The Demko Shark Cub Knife, designed by Andrew Demko, is Demko's answer to requests for a smaller model. This model has a 2.75 inch Shark Foot (sheepsfoot) blade made of CPM 20CV stainless steel, .1 inches thick, with a 2.5 inch cutting edge, a stonewash finish, jimped thumb rest for precise control, and dual thumb studs for ambidextrous one hand opening. The textured black G10 handle, 4.15 inches closed, has a caged ball bearing pivot for smooth action, steel liners for strength, the patented Shark-Lock, and a reversible deep-carry steel pocket clip mounted at the butt end. This Demko Shark Cub Knife has an overall open length of 6.9 inches, and it weighs 3.0 ounces. Made in Taiwan.
From Demko Knives regarding the Shark-Lock: 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.
