Ceramic Knife: Do you own one? And has it chipped?

I love technology —SOME technology. It’s in my job description. I deal with it every day. These knives have ticked zero of the”must have, great to use” boxes for me along with a lot of kitchen technology stuff that just leaves me shaking my head - like wireless connectivity built into my latest stove - why do I want to give anyone the opportunity to hack into my network and remotely turn on my oven? But I digress. The knives weren’t sharp, and you, the user, cannot sharpen them. That’s a bridge too far, or a blade too far. And I’m not a Luddite. I just have acquired come common sense along the way.

I do think technology has yet to find a much better material than wood for cutting boards.

I had a ceramic “utility” knife my dad assembled from a woodworking kit which I loved for about 10 years. Super light weight and easy to use to make infant/toddler sized pieces of our meals without a cutting board. Between my two daughters infancy/toddlering probably my most used knife. Maybe a small chip but nothing serious until I dropped it at the wrong angle and the blade snapped off. Very sad

Ouch. It sounds like it is a customized ceramic knife. Do you think a purchase ceramic knife will do the same job for you?

Cool! A serrated ceramic knife! I have never seen one before!

(It looks like it’s been used to pry stuff, or possibly as a screwdriver. You work with Neanderthals!)

All it takes is 1-2 people out of a whole group to damage the knife. This explains why rental/vacation houses like to provide serrated knives.

The knife kit was from Woodcraft. My dad is a woodworker and retired engineer. I didn’t think I would love that knife so much. But now that my kiddos are older I wasn’t using it as much. I miss it for trimming strawberries and kiwi. For Christmas I might ask if he would make me a new one.

Interestingly he made a similar knife with a metal blade that I do not enjoy. It feels so heavy in the hand. And I have a 75 pound lifting requirement for work

This deserves more than a like.

Am I the only one who’s amused by the harder-the-brittler aspect of knife blade material? Why would anyone want a blade that shouldn’t meet a bone or even a piece of wood? The right shard of glass or flaked obsidian is sharper than any human hand cam make. Do they make for useable knives? The same principle applies to very hard RC steels.

Don’t get me stated on the lemming-lameness of wired technology. That reminds me, I need to post that I covet a clockwork rotisserie and spitjacks…

I spotted this ceramic yanagiba knife – pretty sure it is a Kyocera. It is named as “sashimi” knife and it has a Damascus pattern.


It is being sold for $350. This is not cheaper than a professional yanagiba.
A Masamoto KK Kasumi White Steel yanagiba is ~$250

Remember how the ceramic paring knife (at work) was all chipped up?

We may have gotten a brand new one. This one looks like a larger ceramic Santoku or Chef’s knife, and I just saw this in our kitchen sink, like this. I have a guess what it will happen in a few months.
