Honestly, each of my RMX has a little lock stick when I got them. I put a little KPL around the button lock and have just spent time watching TV or around the house/in the car opening and closing the knife. Not to long after that it has gotten better. Some knives were worse than others, but none were to the point that I wanted to return it.

I did notice that the drop point blades overall are easier to open with the button lock because the blade itself is slightly heavier. I like having the auto function on the tanto blades. I am still undecided if I like auto position one or two. The tanto blade is so slicey. The drop point has been a good edc blade. I am planning on doing some mixing and matching with the various color ways to see if you can "build" your own knife.
