And you just happen to have a Sebenza 25 just sitting in you display case. The only knife I was vaguely interested and n buying at this point in time. You must have been the only dealer in the US that had one in Stock. Okay, now to list a bunch of knives to justify this large scale purchase.

You may need to adjust the pivot a tiny bit. I am sure it will break in though with time.

I know my thumb needs to toughen up. Opening and closing it a billion times last night took its toll, though it appears to be getting a little smoother. Definitely a learning curve on the opening technique. I think you could effectively remove your right thumb print if you do it just so.

Only a billion times? Shall we assume you took some time off to watch the second half of the football game? :)

Seriously, mine became smoother after a while without needing to adjust the pivot. The more I use the 25 the more I like it.
 
A bit of hyperbole, maybe. It was probably more like 200. My thumbs hurts is all I know. And the blue ano on the left side stud is wearing off, I think. Bummer, that.

If you draw an imaginary line between the thumbstud and the center of the pivot, push on the stud perpendicular to that line. That is the angle of maximum leverage to break the detent free. The angle is neither directly outwards, nor too much forward. Muscle memory of this angle is why long time sebenza owners seem to have no problem opening even tight sebenzas. Most don't even realize they are doing it. Once you break the detent free, its just a matter of following the sweep of the thumbstud, but that initial push angle is critical. Callous will help too.

+1 good info
 
Yeah, that detent is a bear. I wonder if anyone has ever peened a little relief ramp into the detent hole to make it a little easier?
 
I used the corner of a triangular ceramic to *very* lightly chamfer the edge of the detent hole where the ball first contacts it on a small Seb. It made a significant difference. NOTE: a little goes a long way, and it would be easy to overdo it, resulting in too little retention, and it cannot be undone. A couple of swipes, reassemble and check.

Good stuff. Yes, one would not want to over do this.
