I wasn't aware that ceramic knife blades could be sharpened. Broken, yes. Sharpened? No.

I'm pretty sure you slap them real hard flat-side up against a rock.












Just kidding....

A diamond hone would work. Slowly though. Yes I have some of those, but I also make knives as a hobby.

I'm an advocate for sharpening your own knives but I'd take a ceramic set to a knife shop and let a Pro do it

Yes, You Can Sharpen Ceramic Blade Knives: Here's How You Do It

or use the option I choose and buy your wife a Buck cutlery set. https://www.buckknives.com/product/13-piece-cutlery-set/0938FAM01/ I always get in trouble when I go to sales at the Buck factory.

FWIW my experience sharpening a ceramic knife left me frustrated. I ended up sending a Boker pocket knife back to Boker for sharpening after I gave up, it came back nice and sharp, than I put it in the safe and that's where it lives. No more ceramics for me.

In a bartender or kitchen guy, you can sharpen them on the rough edge of porcelain, say, undeaneath plates/saucers.

These days people just let their ceramic knives get blunt to such a degree that they are only good for grinding stuff up.. here's an example.

Caligula would be impressed!

Broken yes! She went to teach a co-worker and his huntin' buddies how to clean ducks and broke one.

I may just ditch them. I can get a decent enough, lite enough, inexpensive enough knife to do that.

I did find a video on U-tuby for using a WorkSharp and diamond belt.

That is a nice looking mortar and pestle. Do you get enough grip to grind hard seeds, herbs etc ( ie pepper corns ) ? Mine is more un-finished on the inside, and made of stone.

That is a nice looking set and they are available with Prime.
But should I be better off investing in traditional stone rather than diamond whetstones?

Diamond for sharpening ceramic. I've heard to not use diamond on steel because diamond is carbon and some of the carbon gets in the steel making it more brittle but I dont know if that is true.

TBH, I was never impressed with ceramic knives. they seemed to " wedge " through whatever I was cutting. It was more like cutting with a axe blade then a knife.

hmmm. I have not heard that. I have heard it is not as easy to find a polish level stone - ie over 2000, with diamond.

But, there are a million opinions on U-tuby.
