I have the same knife as Jesse B. and tested it as an EDC for over 6 months. Just now got a chip in it from slicing a lemon and drawing down on to a maple cutting board. Being ZrO2, I no longer consider it "safe" now that the edge has been compromised.
I will say that it was a great gentleman's blade while it lasted. Very light, fast draw and reasonably sharp (not shaving sharp though). I'm kind of sad, I got quite attached to it over those months but I think i'm going to stick with one of my other vg10/s30v blades for EDC from now on.
Maybe I'll try another ZrO2 blade from a better source. It would be cool if they made something a bit more durable in the ceramic format. Although, I really do like pushing the envelope on sharpness which is something that is a pretty short walk to diminishing returns when it comes to ceramic.
From what I've read you do want to stick with the black ceramic over the white ceramic... Good luck.
