I have no experience with CRK customer service and quite a bit of experience with RHK customer service. RHK has been incredibly inconsistent between what’s been said and what’s been done. In short, I was told warranty service on the lock or blade play would have a lock bar insert added. That didn’t happen. Anyhow, I have heard horror stories about CRK denying warranty claims because lockbars are too worn or someone “abused” the knife by supposedly “flicking” it open. I think what’s happening with the small production companies is that RHK is likely to warranty the blade in the event of an in-use break, where CRK would likely charge you for the replacement for one reason or another.
