Here's what I would do...
Call them on the phone.
Try to get the manager, but not absolutely necessary.
Get his/her name.
Ask your question.
If the answer is YES, then you can order it right then on the phone.
Since you have his name, the probability is that you'll get one picked as you requested...maybe.

Make certain of the return procedure. You know that they do NOT want to get it back.
As usual, caveat emptor.
NO...SCRATCH ALL OF THAT ABOVE.
YOU ARE ORDERING A SEBENZA. IT WILL BE PERFECT, AND SMOOTH IN OPERATION. THEY ALWAYS ARE, IMO.
I've had at least twenty Sebenzas. Sebenzas are PRODUCED as to ALWAYS have a centered blade, even after you take it apart to clean it. CRK has videos that help/suggest you take it apart, yourself, for cleaning or inspection. Warranty is fine before and after.
The lockup will be solid; the lock-bar will be at about 80%...where Chris Reeves wants it to be. It will NOT move substantially at all, with time/use, or CRK will take care of it for you.
The grind will be even, as that is part of the item you are paying good money for. I've never had one that wasn't perfect...even though EVERY ONE of mine has been purchased "as-new" or "slight wear" in the Exchange. A CRK Customer Service spa-job will restore any Sebenza to like new again...for about $17 (shipping expense, IIRC). The spider-trails on a used knife will be re-blasted as new. If you damage the blade, you will likely have to pay for that repair...as you should. Re-sharpening the blade is free.
And...YES, you can return it to BladeHQ if I'm wrong. I've dealt with them before with other folders. Zero problems.
The knife has a lifetime warranty. If you ever tire of it, you can EASILY sell it on the Exchange for little loss. A large Seb with "slight use" is likely to sell between $325-$350 on the Exchange. Of course, fancy models...inlaid wood, whatever, would be higher.
It is my long-held opinion...there is no finer folder. I've had many folders up to $800; never one as nice as a small/large Sebenza.
I carry my Umnumzaan every single day. The Zaan is made with the same care and precision as any Sebbie, but the Zaan presents a slight tactical appearance that I enjoy. I did once carry an old Classic model large Sebenza with scratched-up titanium slabs for about a year. I loved it...smooth as silk. I sold it in a moment of idiocy...still regret it. I do have two new large Sebenzas in the safe.
Of course I'm a fan-boy. But I became one through experience with MANY Sebenzas, small and large, plain slabs and fancy inlays.
