Ceramic Knives

I have just gotten my first Kyocera Ceramic knife for galley use.
I must admit I'm impressed by the edge.
I am considering getting more.
Is there any downside to having these knive aboard?
They are sharp and dont rust ... big plus for that.

Re: Ceramic Knives

Easily chipped, and when they do indeed get dull? A powered diamond sharpening grinder is recommended.

That probably could take down enough blade to get rid of small chips, too.

I bought and drank the KoolAide, was briefly impressed, but have gone back to good steel kept to a fine edge.

Re: Ceramic Knives

Personally I think they are great for onboard use. Our experience suggests they do keep a sharp edge longer than steel and after, I guess, five years or more of use I've yet to chip one. We have one of those pull through knife sharpeners which I know are universally condemned by the pros but they work for me, who is not a pro, just a plodder who likes to cook.

Re: Ceramic Knives

I've chipped too many of them (dropping them, torquing them, dropping something on them, etc) to get more. Modern stainless is good if rust is a concern. I actually like carbon steel, even on a boat, because of how easily it takes and holds an edge.

Re: Ceramic Knives

I have a few Kyrocera cuisenart and harbor freight. I am not all that impressed and prefer well maintained steel knives. French or Japanese steel. Ceramics are good for cutting high-tech lines.

Re: Ceramic Knives

I guess I'm just not as clumsy as some. I have two damaged knives at home. None on the boat. One is stainless, the other plain steel.

That said, we don't live aboard so are only on the boat for a couple of days a week. I'd guess that once we are full time we'll probably have all stainless if only because they are nicer to use.

That's the only thing I use them for, they're awesome for cutting spectra, if you're splicing Amsteel, or whatever...

Nothing better for that application, they're the choice of the pros, ceramics are what the crew of RAINMAKER grabbed to cut their hydraulic lines and running rigging in jettisoning their downed rig, after all...

Re: Ceramic Knives

I love mine as a pocket knife, but I am not sure about their use for kitchen knives

We bought a basic Wustoff knife set for the boat back in 2008. Like Andrew we maintain them with a handheld sharpener. So far not a spec of rust on them. After nine years of weekend use they still look new.

I think you could use most any quality knife on board as long as you take care of them.
