I would like to try buying a ceramic kitchen knife like this

just mostly out of curiosity. Has anyone tried them. Thanks

Haven't tried them personally. They're supposed to be very sharp and
stay sharp, but they are of course relatively brittle, so unlike a
conventional steel knife you can break it fairly easily. I believe the
infamous Harbor Freight carries one or two models.

I have the HF 5" model, it is tough & sharp and doesn't stain or rust.
It seems sharper than steel, and easily cuts the tough plastic bubble
packages better than anything else i've tried. IIRC it is non-metallic
and missed by metal detectors and I believe it is considered 'plastic'
by TSA
