For less than $16 dollars shipped you reliably can buy direct from China an Enlan EL-01, manufactured by the very same outfit that makes Spyderco's value line, Byrd, as well as the Spyderco Tenacious and it's cousins. You get a VERY beefy liner lock, practically indestructible, with great fit and finish and an original design, G-10 or rosewood handles, flipper opening, and a very good 8cr13MoV blade. One of the best values in the knife industry if you can move beyond some preconceptions.
