OK, on the issue of accidental opening in the pocket: I use the flourinated grease that CRK sells. Seems to dampen the motion of both opening and closing the blade. I probably take my Sebenza apart every month, totally clean it, apply a small amount of grease to all pertinent surfaces, then re-assemble. I've never had an accidental opening with this maintenance routine. I bet lack of regular maintenance, or using a light type of oil on the surfaces has something to do with accidental opening.
Now, as to "negatives" on the Sebenza, here goes.
And realize that I'm being completely anal as none of these comments really bother me, just trying to play devil's advocate.
1. blade shape and material- for me, the blade is the only thing that I have no "negative" comments on.
2. handle shape and material- could be more ergonomic, however, by being the way it is, it allows multiple grip positions and minimizes the profile in your pocket. The one thing that really does bother me is the slightly sharp ends and other transitions on the handle slabs. Seems that CRK could've completely rounded them for better aesthetics and less tendency to wear thru your jeans.
3. lock performance- Perfect, NOW! I have real long-term concerns here. Seems that the lock-up point changes slightly after re-assembly, presumably from different rotational position of the stop pin. What I really worry about is: is the lock bar itself wearing against the hardened steel blade tang, or is the stop pin becoming indented/worn from multiple openings of the tang against it, or both. I can forsee a day when the lock bar travels all the way over to the handle slab. After this happens, blade play is inevitable.
This is something that CRK has never addressed but really should.
4. opening method- I like! I'd probably prefer an opening hole, but this would definitely affect the aesthetics of the Sebenza blade by making the opening hole area jut out further. Besides, the blue anodized stud adds a bit of color and style to an otherwise plain appearing knife.
5. carry and deployment- I like tip up carry. However, it would be nice to have the option of tip down also.
6. overall fit and finish-oh wait, nevermind.- The only comment I have is that the screw which holds my clip on was ever so slightly too long and protruded past flush on the inner surface of the handle. This bugged me so I removed it and filed it down carefully. Voila! Flush fit.
And while I'm being anal, the extra hole on the front of the handle is unnecesary and visually distracting.
Like I said, none of these are show-stoppers (except possibly the lock-bar/stop pin wear problem. But I really think that if it gets bad enough, CRK will make it right.
My $.02.
