null,
I'd argue here that if what you're trying to do is pick up something that performs like a Sebenza, but for less money, you're looking in the wrong direction. One of the key things that makes a SEbenza a Sebenza is that the Sebenza's framelock is so much more reliable than a liner lock. Liner locks are one of the most difficult locks for a manufacturer to consistently get right. With a framelock, the thicker lock/tang juncture gives the manufacturer more room for error, and the fact that when your hand goes around the knife you actually reinforce the lockup makes the framelock even more reliable.
My strong advice is that you should be looking at lower-cost production framelocks, axis locks, lockbacks, or compression locks that fit your needs. Are you looking at this as a last-ditch survival folder to help whittle fuzz sticks, cut cordage, etc.? There's lots of good options here. What you're looking for is a reliable lock, good quality steel, and the proper blade geometry for this type of use. I'd argue that the following could all fit the bill, at various price points: Camillus Dominator, Spyderco Chinook II, Benchmade 710 Axis, Benchmade Griptilian, Spyderco ATR.
