Does it have any advantages? I recall seeing one Japanese kitchen knife made out of it long ago, but it wasn't cheap and I wasn't very curious about it, then.

Kyocera's zirconium ceramic kitchen knives hold a working edge almost indefinitely. They just keep cutting and cutting and cutting. Don't pry with it, don't chop with it, don't twist with it. It's not a boning knife.

i agree to chop, twist, or pry with it. it is very brittle. the stuff was meant as industrial abrasive.
 
HEY!
There's a big difference between Zirconium and Zirconium Ceramic!! Pure Zirconium is similar to Titanium but quite a bit softer! It will also anodize like Ti. It's also flamable like Ti.
It would not make a good knife blade at all! I'm not sure of any alloys based on it that would either.

When I saw the knife and heard "zirconium" I also thought "ceramic", but I don't think it was, as it looked quite metallic.
 
I think of it as an abrasive used in sanding belts. It makes for an excellent sanding belts. I use the blue ones sold by Home Depot in the 3x21 size. They make my old Crafstman belt sander come alive.
