I've got the Cara Cara. Rock solid. No blade play whatsoever. As "Roger999" stated, my lockback is just a bit difficult to disengage, but that's fine with me. It's not stuck, just requires a forceful thumb press. For the price I paid, I'm happy to cut everything with this knife and not feel bad about it later on. After plenty of outdoor food preparation, general outdoor use, and some cleaning I can't find any stains at all. By the way, the Cara Cara is quite big. I can't EDC it because the office staff would be shocked.
