Yup, this, or a compression lock, or the tri-ad lock. With a framelock or even a liner lock, the potential for wear to loosen the lock is much greater as only the face interacts with the blade. On the three locks mentioned above, the lock actually forms a wall against a cutout section of the blade. This means that even if wear develops the lock will still keep the blade in place as opposed to slipping off to the side because there isn't enough contact between blade and lock, as on well worn liner and frame locks.
That isn't to say there aren't awesome liner and frame locks out there. I just find them to be inferior locks and prefer more expensive knives to be more reliable than that. Plus you always hear about having to "break in" a framelock. Forgive me, but I've never had to do that with an axis or compression. Smooth as silk.:thumbup:
