I've got a Boker ceramic.
My brother does too.
Pros-
-Scary sharp
-They stay scary sharp for a long time
-They're easy to clean and don't stain
-Light
Cons-
-Brittle
-Expensive (or they were last time I checked)
My brother took one of his Boker ceramics to work with him one day, and knocked it off the counter. The tip of the blade fractured and came off. It is still usable, but missing the tip, so don't bang them around or drop them...and no battoning!!!
Again, a reminder: These are likely to be the sharpest out of the box cutting instruments you've ever seen (scalpel sharp, razor sharp, broad head arrow sharp), so BE CAREFUL.
