Found 12th Jul 2010Made hot 15th Jul 2010
Ceramic knives are supposed to be incredibly sharp (and very expensive). I'll look forward to trying these out.

They're also doing 15cm knives for £9.99

Alright until you drop em and they snap

Similar warning; don't keep them in a drawer with other knives as these can chip easily.

However, great knives - especially for fruit and tomatoes.

Good for bypassing metal detecting devices too I guess?

I think the manufacturers have to put a small amount of metal in, just because of this.

How would you sharpen it? It must eventually dull.

Apparently they're great for chopping lettuce as it doesn't go brown after (or so I hear). Is that an urban myth? I hate Aldi for closing our branch down. Road works for 3 months meant hardly anyone went there, the road works finished and they shut the store.

lettuce will still go brown with these as they break the cells on the leaf.
its the blunt serrated plastic ones that are supposed to not because it acts like hands ripping iirc

You need a diamond sharpening stone - certainly don't even think about using an ordinary steel on them.
But clearly the future is disposable ceramic kitchen knives - like disposable razor blades.

I got one of the small knives last time Aldi had them.
Personally, I was a bit disappointed with the edge.
If you have a drawer full of blunt knives, then this might be a scalpel for you. (Don't store it loose in a drawer - you WILL cut yourself.)
I think that overall you'd be better off putting the money towards a proper sharpener for your existing knives - something several steps beyond a simple steel.


Ceramic knives are indeed delicate - don't drop them or bump the blade into anything hard!
And don't try to use the knife as any sort of lever - they simply don't flex, they snap!
But they are super-light and provide the strange sensation of caveman-style cutting with a flake of flint ... some others might liken it to cutting with a naked razor blade (but it ain't that sharp!)

Picked up two of these today (one of each) as I was interested as soon as I got the 'Special Buys' email. They do seem good and sharp, will look forward to using them in anger (on inanimate things of course :D)

too bad , not online, any other cheeeeeep online alternatives?

Nowhere as cheap as ALDI I'm afraid.

Cheapest UK sold one I can find is here. If you don't mind a delay then eBay USA has this.

I bought a ceramic knife from Tschibo a while back, just because it was 'cool'.

It looks nice and is sharp for sure.. BUT.. The blade chips easily.. I have not mistreated it by any means, but after a few uses I noticed that there were tiny bits missing from the blade..

I certainly wouldn't buy another Ceramic blade again..

got a few off deal extreme last year went for the black blade (more pretentious) and they do put metal inside them (xrayed mine at work ) so you wont be able to take on the plane in your carry on

For that money you could buy a small Victorinox knife, it will stay sharp for years and it's quality.
Sorry, I rather have a couple of good knives than a drawer full of blunt useless ones.

Either way not voted.

I'm just intrigued by this...."xrayed mine at work", did you take it to work just to xray it? Did no one think it odd that you turned up at work with a knife to xray???

Stunning deal. Bought a bunch, some for home and some for presents. Tried mine this evening, worked like a dream. Best to keep them separately as they do chip and they are and stay sharp a long time.

How it's made


Interesting, thanks.

Nice video on how they make ceramic knivesKyocera Ceramic Knives



Haha - "Kyocera is short for Kyoto Ceramic"; so how come they also make printers and touch screens?

I've got several of the Kyocera knives (which were a LOT more expensive!) - as with any knife, if you look after it then it'll stay sharp for ages. If you just throw your kitchen knives in a drawer then a) THAT'S REALLY DANGEROUS and b) it'll go blunt quicker whatever it's made from.

Yes it does chip and if you drop it it *can* shatter, but they're hardier than you think. If there's enough force to chip it then there would have been enough force to damage an equivalent metal knife.

i got it delivered to my work address and we have a xray machine in our post room so xrayed it there
no one thought it odd

Wonder where they went?? oO

These are meant for slicing only rather than chopping which makes them almost useless for general use which is why you can get ceramic bladed mandolins now.

Worth getting one for curiosity sake though at £5 a throw. Just don't throw it.

Bought this one , plus the larger normal blade , and the larger ''bread knife'' blade.
All very nice cutting blades.
Mine will stay in their containers when not being used , less chance of a ''broken'' blade

Used mine a fair bit of the weekend (any cutting job I had X)) and they're very good indeed.

Went back to ALDI for the bread knife this morning (didn't realise they were doing one 'til I saw the above post) and they had totally sold out of all types.
