Ceramic knives

by carla griffin » Tue Apr 07, 2009 12:14 pm

I saw these for the first time in a store the other day. The little sign net to it said they keep an edge 10X better than a regular knife.
What say yee forumulites? Have you ever used them? Are they all that great? Do they keep their edge better? Are they worth the bucks? Should I invest?

Yep, they stay sharp a lot longer than you can go without dropping it onto the floor and shattering it! Nobody knows how long they stay sharp!

Several years ago I used a Boker ceramic knife for a lot of my camping/outdoors needs. The blade stayed unbelievably sharp -but- I was not very happy with the durability...the blade was VERY brittle and I had the knife replaced twice due to the tip breaking. Please note this was over 10 years ago, so
I have NO idea if manufacturers have found a way to address this issue.

I have seen a few small Kyocera knives for sale at Williams-Sonoma before.

Here's the deal with ceramic knives... you can't sharpen them yourselves.
You either get a new one or find someone who specializes in sharpening them (you're probably going to have to mail it out).

They can't take the type of abuse a steel knife will though.
You need to stay away from bones, anything hard, etc.
They are incredibly brittle, and if you're prone to dropping knives... you might be better saving your money.

A former co-worker of mine had a small 6" Kyocera that she used exclusively for herbs. Perfectly cut, ultra-fine thin chives, parsley, basil chiffonade, etc...

For someone who is a serious regular home (or a professional) cook, and can justify a knife for a specific purposes... then go for it.

If not, just get a nice knife that feels right in your hand, and (important!) is soft enough to easily sharpen yourself, but not too soft that it dulls every other week.

I used to swear by Wustoffs, but have switched to Japanese knives recently: they start sharper in general, and are easier to sharpen once the edge is gone



Speaking as a professional: One of the next knives I buy will be a ceramic knife for herbs.
