I just purchased my first Chris Reeve knife, a small sebenza 21. I had read that the way the pivot/bushing system works is that the pivot and bushing lock together and the blade rotates around the bushing. When I took my sebenza apart to re-lube it, I started to investigate this interesting bushing system and noticed that when I placed the bushing around the pivot, the bushing did not lock in but freely spun around the pivot. My question is this: does the bushing and pivot only lock together when you put the knife together and tighten down the pivot or did I read something that did not correctly describe how this works? Thanks in advance for any responses.
 
First of all Congratulations on your first Sebenza. You have made a fine choice.
When the blade, bushing and washers are inserted between the frame, and the pivot tightened, the bushing is held ridgid between the frame so it does not move. The blade then rotates around the pivot with just enough clearance on each side to allow the blade to rotate between the washers, but not enough to allow blade side play. You will appreciate these very close tolerances in your new Sebenza and this is why the blade has a more "hydraulic" feel when opening and closing. Kind of a bank vault effect so to speak. I hope this helps and that I have not made this seem overly complicated. :)
 
I'll have to compare the opening of a Sebenza to the opening of a bank vault real soon now to see if your comparison holds true.
