Good. I need a better knife sharpener.

Well at least now I have a diamond for the missus if the sharpener is crap.

Oh my. I guess people know that knife sharpeners can be had for 100 yen, right?

I wonder what is happening to civilization. How much are we willing to spend for convenience and novelty? Truly the sky is the limit. The same people who would buy can openers for 10,000 yen complain to high heaven about paying 10,000 yen in taxes to help poor single mothers. All of this is a sign that humanity has its priorities mixed up pretty badly.

Klein2 - I guess you never used a ceramic knife before. For your information - it will simply destroy your 100 Yen steel knife sharpener. Ceramic knives can only be sharpened by diamond, and this is actually the first consumer grade sharpener product I know of. Until now I always had to send my ceramic knives to Kyocera for sharpening (once every 2-3 years, or so)

Kyocera brought out a diamond sharpener for its ceramic knives a couple of years ago, costing around 1400 yen. It works fine. I wonder what makes this one so much better, to justify the price increase?

cleo - did they? I was never able to find one, anyway. This one is electric and it has a handle :))

Some people just want the best and are happy to pay for it. Simple as that. As for poor single mothers. Let them use a whetstone.

Put up a few signs advertising your new diamond knife sharpener (ceramics too!), set up shop in front of the local supermarket and put that ojii-san's traditional weekly knife sharpening service out of business. ;)

Ceramic knives chip easily. I would never use one again.

i got a ceramic knife and the tip chipped within a month. the edge is also nicked up. i probably won't buy another ceramic knife again.

When you buy a ceramic knife it comes with a warning about nicks and chips. If you can't use a bit of care when handling the knife, better buy a metal one in the first place.

I love my ceramic knife. It's lightweight, doesn't rust or stain and cuts like a razor. I don't use it for heavy-duty banging stuff (like flattening garlic cloves and tightening screws :-)), but for cutting, it can't be beat. And the edge lasts like ten times longer than the edge on a metal knife.

ebisen - I found it featured on the Kyocera HP, then found a seller on Yahoo! Shopping. It's got a handle....but it isn't electric. So that's where the price difference comes in.... Mine is more eco. :-)

Who sharpens their diamonds? We have some rich folk with too much time around here.

It's not a diamond sharpener, it's a kitchen knife sharpener. And an expensive one!

OK - I actually bit the bullet, bent over and bought one - took 17 hours to deliver from Amazon, and yesterday I actually sharpened one of my knives with it... All the nicks are completely gone, and it cuts like a razor. It is electric and the diamond tools (two small disks) are actually kind of silvery and sparkling shiny... As a result, there is a very fine powder (like talcum) after you finished sharpening the knife
