Um, you shouldn't have thrown it away.
The major ceramic knife MFG's offer resharpening service for their blades,a s in most instances, the owner can't do it him/herself.
I think Boker charges $19.
Kyocera may do it for free...
Regardless, throwing away an "expensive" knife might have been a bad move.
FWIW, my ceramics still pop hair 8+ years after buying them.
Hey Pitbull, just wanted to say thanks for all of your input and information. I really appreciate it.
