"sintered diamond plates" from 150 to 12K !!!!!!!!

These plates differ in that the diamonds are sintered to the steel substrate by using great pressure and heat. As a result, the diamonds are more likely to stay in place, even under the most demanding circumstances as they are effectively part of the substrate, not just stuck to it.

All this adds up to a diamond plate which shall continue to work long after a lesser plate has shed it's diamonds and can be used more 'vigorously' as the diamonds are more securely held in place. Simply put, these plates can handle the pressure, as much as you care to exert upon them.

Constructed as a diamond/steel/aluminium 'sandwich', the thick aluminium base plate offers incredible rigidity without adding unnecessary weight, while the steel offer a resilient base to which the diamonds are fixed.

This #12000 grit is intended for final honing of plane blades and for steel blades that are known to be difficult to sharpen to a very fine edge by 'normal' means such as sharpening stones or honing compounds.

i'm broke, who wants to buy a full set for the team ? :D

it's just about 800 dollars ... :eek:
 
I might actually sell my DMT's for those..... well maybe.

I don't see a micron rating, do you have any idea what the 12k would compare to?







P.S u suck :)

yeah i know

no idea i think it will obviously be JIS rating so perhaps the 150 is a bit slower than 120 dmt.

my main concern is that as the diamonds are sintered in the steel plate the grit rating may be altered.

i wonder if the rating is done before or after sintering, this may change the way it work big time.
 
Diamond abrasive should be rated in mesh and micron but everyone has their own "grit" so it would be hard to say. If it is equivalent to JSI though then I'm sold.
 
Cool, I hadn't seen the sintered ones before. I tried for quite a while to source the electroplated without the base in a decent grit for use as disposable lapping plates, but I couldn't get a reply from the manufacturer (guess I need to learn some japanese).

I do wonder about heat and pressure applied to diamonds while contacting steel, all the diamond grinding tools say never to use them on steel, only non ferrous metals and non-metals. Iron's affinity for carbon plus the heat/pressure causes the diamonds to break down and the carbon to be absorbed.
 
I am certainly interested in this, as well as all new technology.

Nevertheless, DMT is a time proven and well known product. I would find it necessary to gain pertsonal experience with this technology, or at the very least be made aware of a proven "track record" before abandoning DMT. :p
 
They look good, but $157 and shipping for the 1000g to start seems steep to experiment with. Unless they do everything amazingly well, that is more than double the cost for DMT stuff.... Hmmm, maybe they do do everything amazingly well. :D

It would be my opinion that the preferred venue for testing, and establishing a "track record" for these tools would be the "professionals" among us.

They would use them enough to quickly gain insight into whether or not the additional cost is justified. And of course, that cost could be amortized at tax time as a business expense.
 
I just found this thread and it made my day! :)

These are the 'latest rage' sharpening stones found in all the discount stores here in Japan. You see them in the 100 Yen Shops (Dollar Stores to you!) and in the discount bins around the cash registers in home centers, Department store Kitchen floors, and DIY shops. They are everywhere now!

This reminds me of the day when someone from the US was proudly bragging to me that he imported some 'Naniwa' motorcycle gear. I didn't have the heart to tell him that "Naniwa" is the "K-Mart" or "Walmart" of Japan's motorcycle shopping. Good, but nothing to write home about. These stones fall into the same category. They work... but nothing to write home about. I'd stick with DMT.

Sad to hear that, seems they are a little over hyped then?

I think all of us get a little excited when we see something new being offered by a good company, and often give it more credit than is due. Right now, diamond sharpeners are all the rage in Japan, and you find them in every size and shape, being suggested for every type of sharpening you'd ever want to do. Tiny ones, triangle-shaped ones, huge things the size of a chef's knife, little ones that look more like toothbrush size... And all of them claiming to be "THE" answer to every sharpening need.

The fact is... they work. They just don't work as "THE" answer to 'our' sharpening needs. Those of us here tend to be rather picky with the resulting edges... to say it nicely. These things will work great for our neighbors or our cousins. Hey, they are diamond sharpeners, right? They work. I just wouldn't spend all my rent money on them so quickly. They are pretty generic, despite the fact that to people in other countries the fact that they are "Japanese" somehow make them extra special.

It was the 12k plate that was getting most of my interest, that's pretty high and would be perfect to follow the stones I have now.

There is nothing 'wrong' with the plate. And a 12K would be nice to have... But frankly, I don't think you'll be satisfied with the edge.

The web site is showing me the prices in Japanese yen. I don't know what you see when you access it, but at ¥15,495, that's three times the price that it sells for here. At ¥5,000 it might be worth playing with, but not ¥15,000

Actually, in the shops I only see the lower grits being offered, and those for ¥995.

As I said, there is nothing 'wrong' with them, but there is nothing extra special about them either. I bought one of the lower grits last year, tried it a couple of times and shoved it into the back of the closet.

ouch, that's a nice increase.

the lower grit sure have nothing special, the sintered plates starts from 1K below they are "classic" diamond plates ... but if you tell me they are not worth this price i'll try to source them from another dealer. maybe the big japanese marketplace i don't remember the name.
 
The Internet often attracts people who look for more expensive items believing them to be better. So it behooves the business owner who wants more profit to simply raise the prices that he offers his merchandise. This has been clearly demonstrated right here in this newsgroup with a company that is selling stones, sharpeners, and other equipment for half-again as much, and more, than the original manufacturers. I don't recall the name of the site right now, but I made another post about it a couple of weeks ago when someone asked for info about them. I compared their prices and found them to be significantly higher and posted that fact. This didn't seem to deter people from dealing with that company. I really don't know why someone would want to pay $400 for the same item that they can buy from the manufacturer for $300, but we all get the choice, I guess.
