Well, you can buy one and see for yourself.

Careful you don't cut yourself.

I've had a couple and yes, they are sharp and hold it for a long time.

Thanks. Good to know.

It's not mainly about being sharper, a steel blade can be sharpened the
same as a ceramic blade and vice versa, the issue with ceramic is they
hold their sharpness much much longer than a traditional steel.

Can the ceramic knife be sharpened at home without any special equipment
when it does become dull ?

There are sharpeners but I have no idea how well they work.

Diamond sharpened I guess. I use the ceramic rods to sharpen steel knifes.

Use a Dewalt reciprocating saw with a smooth/knife blade.

I guess if you drop it on a hard surface it is going to break. A good
knife can last many years and sharpening is not that difficult.
Apparently ceramic knives stay sharp much longer but to restore a good
edge might require sending them off to be resharpened.

Correct on breaking. Many butchers us knives from a service that comes
in and sharpens them, replaces them, etc. They get a lot of hard use.
While great for home use, I don't see them working as well for a butcher
that does more than the typical straight cut.

"Ordinary kitchen knives" are not sharp at all, unless you

through a banana, and I'd be forced into a life of decadent

Brittle and easy to break would be one good reason.

Some people destroy their knives within minutes of taking them out of the box.

The proper way to cut with a knife is with light downward pressure and a back and forth sawing action.

If you slam it into the cutting board (like the TV chefs), you'll distort or roll the cutting edge. Then you have to resharpen.

They are brittle. That's something to remember when sharpening them too.
When sharpening conventional knives many people introduce a bending
force to the blade. What you don't even notice when sharpening a steel
blade with snap a ceramic. Diamond stones aren't 100% necessary if you
don't mind taking hours to wear down the edge.

Another thing from the conventional technique; feeling for a slight burr
on the off side edge won't work with ceramic.

Steel, preferably carbon and not stainless, has sliced anything I've
needed to slice.

I prefer a sharp knife for vegetables (for everything, really).
It's much safer.

Never use a normal sharpening steel on a folded-steel knife.

Probably the best reason to avoid them.

I'm sure those knife sets that are sold are already sharpened.

take care of them and they're still sharp.

Interesting.

When I was in high school my brother was in med school. He was cutting
a tomato and the topic came up, so he showed my mother and me how he was
taught to cut a kidney. What you said plus after going part way down,
to flip it over and cut from the other side, so that the knife didn't
hit the surface and damage the knife.

He used to hide disgusting things under his bed. One was a greasy paper
bag that I think he said had part of an arm in it. I'm not going to
look. We shared a bedroom but he was good enough not to open the bag
when I was nearby.

Few people have a steel to keep them in shape too. Even fewer know how
to properly use one.

I own a steel but almost never use it - I prefer the little
diamond stick like a mini steel

http://www.leevalley.com/en/garden/p...t=2,2160,40710

Just a few swipes on each edge, a few times per year.

I also use it to touch-up the long serrated bread knives - it's a
bit tedious - one curve at a time - but it's once-per year.
and I don't know how else to do it ..

A full-sized diamond steel is available but a bit pricey :

Why on earth do you buy new knives ? Mine are all 40 years
old. Scissors too. I bought too many thinking they would wear out.
They didn't.

Re sharpening:

A steel just straightens the blade. You need a stone to
actually hone it (not too often). I have an old leather belt from the
hippy 70's (4" wide, an ex-girlfriend I can barely remember threw it
out and I salvaged it) to "strop it".

I have a genuine imported Russian leather strop with the linen belt on

Agree. Very, VERY sharp (the Harbor Freight ones) and they hold an edge
for lot longer than steel (provided you don't drop them, in which case
you'll still have a very sharp edge, but a LOT of them and very short
lengths)

Even sharper, look up "obsidian scalpel." They are fashioned from
volcanic glass and are so sharp that some surgeons still use them for
delicate surgery. They are said to have an edge so fine and sharp that
they actually cut the tissue cells in half rendering an incredibly
smooth cut and promoting faster healing.
