I have wanted a CRK for years. Ordered my 31 yesterday, will be here tomorrow. Fingers crossed I don't have any issues. If I do, I will likely return it, 2-8 weeks time frame for repair is a long time for a brand new ($500+) knife. I had found this thread before, hemmed and hawed over it and decided to pull the trigger. The retailer I used is very good about CS in my experience and has a good return policy but hopefully I don't need it. Seems like it is a crap shoot. Seems weird they wouldn't make more significant changes to the lock bar to accommodate the ceramic ball. I don't expect a $500 knife to be perfect by any means, it isn't a custom that costs several thousand dollars but if I get one with bad rock, I will have to send it back. I don't care how long I have wanted a Sebenza, if they aren't up to the quality of the few others I have ran into over the years, I will send it back.
