Never gave it a thought. Actually, I had to pull out my backlocks - 3 with dents, 2 without - to see how I feel about each knife. Because to me there is no consistency how one feels vs the other. To me, the more noticeable difference is the tension of the lockbar spring.
The P4 and the Native, without the dent, both have very different tension on them. Even the two Natives I have feel different in this aspect. Similarly, the Endura, Delica, and the Caly, with the dent, all have different tension in the release mechanism.
So, yes, makes no difference to me. I always accepted the way they disengage the lock, each having a different feel to them.
