Ceramic Knife Sharpening

Post by Kidcook »

Bought daughter a very nice set of Kyocera ceramic knives some time ago when free lifetime sharpening was part of the deal. Now, it is not. They make an electric sharpener they sell but the reviews are terrible. I've been researching sharpening ceramic knives and free-hand diamond plates seem like the thing to try. I would say I'm a moderate to above average whetstone sharpener so willing to try if I'm on the right track. Mark sells an Atoma #1200 but it looks like DMT plates seem more for sharpening.
So questions:
Am I on the right track trying the diamond plates? Has anyone sharpened on the Atoma #1200? Has anyone sharpened ceramic knives with any positive results on anything?

I think using diamond stones in a resinoid binder would work better, or vitrified diamond. I confess I have not tried

Ok, I'll look into it. Going from free lifetime sharpening to basically no sharpening service totally makes these knives worthless unless I can do something about. Thanks Cliff...

It's a drag. You may be able to use plates to sharpen them. I really don't know. Those stones I mentioned will set you back more than a new knife, so it's not really worth it unless you also have some high carbide steel knives.

Ya, I totally hear you. I've got shapton glass and pros for that matter. A couple of Choseras as well. If i could get away with just one diamond plate maybe it wouldn't be that bad, hence the post here. Do you think if I bought her a Carter she might switch?! haha
Thanks for mulling it over and giving it your time Cliff

Maybe try diamond sprays on strops?

Ya, I get that. I contacted Kyocera and they talked me into their battery operated sharpener. For forty bucks I figured I'd give it a try. But I've got diamond spray on strops so it"s no cost to me to give that a try. Maybe some combination of these will do the job?! Thanks Taz

Update, the Kyocera battery operated sharpener was a flop. Not near enough power to do any real work. Also, the diamond wheel was spring loaded with not enough tension. So I returned it and picked up a small DMT double sided diamond plate 600 and 1200 grit for ten more bucks. This was the way to go. I ended up only using the 1200 side. Ceramic come off totally different then steel but after getting a feel for it it got the job done. I finished with the diamond strop and that help as well. Wouldn't have been able to sharpen it with just the strop though. Thanks again for all the suggestions. Learn something new everyday!
