I love liner locks as well. On a good knife, a liner lock is really strong. Take the Military for example, in tests, that liner lock stood up better than most other locks. I don't know where the myth about liner locks not being stong started but we as informed knife lovers should look at the facts and not be taken in by all the hype. Liner locks are very strong if done right. A poorly done lock back will fail just as soon as a poorly done liner lock, I promise.
Anyway, is there anything more natural than a liner lock/frame lock in the hand? I guess the back lock is better for left handed people but for us normal right handed people that the world was designed for, the line lock is great.
Looking forward to that CF Stretch as well! I really like the regualr stretch but a lighter version would be nice. As long as they keep it nice and slim, I think it will be a winner.
