DMT - How good? How reliable.....

The best all around stone is the red 600. I use the black extra coarse, then the red fine and then I go to a Arkie Translucent. I get great results. The DMT's are really long lasting stones. I am looking forward to buying a 120 grit but I might go EZE-LAP instead because the DMT is not available where I live.
 
DMT saves wear on irreplaceable vintage stones, at an affordable cost. I don't know what level of wear is acceptable to you, but as they're a commercial product and replaceable, and very enduring for their cost.. it's not a question.

They work good, they don't do everything but what they're good at they're VERY good at, DMT is a no brainer. The only question is do you need a particular size or grit. .

I'm quite addicted to natural stones, but DMT & Shapton give you all the value you pay for and then some. There's no reason to question their efficacy or longevity, just be sure you need the one(s) you buy, and you're fine.

You might want to clean those out with a scrub brush. They don't wear out anywhere near as often as they get impacted with steel dust.

i scrubbed them clean with solvent quite frequently during the reprofiling. I suspect too much pressure was the culprit.
 
Weird. I overdo it quite a bit with the pressure and my diamonds are still going fine (only the D8EE has scars). Maybe they've just lost that super-fast cutting action? When they're new, they have a bunch of extra diamonds on top of the ones bound in nickel, but they wear off after a few sharpenings leaving a surface that doesn't cut as fast as when new, but still on the fast side.

I thought I wore the diamonds off my 204D hones after rebevelling two knives, but they're still going strong years later.
 
I've been considering getting a set of DMT diamond sharpeners. I have a blue slotted one which I found in my late dad's junk box, but it's too coarse for fine-edging.

Does anyone know the DMT "grit vs color code" for their small (~1.5 X 3" ??) "stones" ?
I browsed their website but couldn't find it. :(

Your welcome flashlife however I could not find the Tan one online dealers that is.. Must be a rare one.

After reading this thread, I wonder if I'm using too much pressure on my DMTs. Pressure seems to be a bit subjective, except for "only weight of the knife" pressure or suchlike. Would the pressure of, say, the weight of a D8XX be too much for comfort for most of you?
 
They work well, easy clean up with water and some Ajax. My oldest DMT stone is 8 years old and doesn't show any wear. I prefer the DMT stones over my Norton oil stone due to the ease of clean up.

Diamonds are the hardest material on this planet to my knowledge? My golden rule is apply a little much more force as gravity.
LISTEN to the sound it should have a middle pitch when grinding. (this may look vague to you but i started listening when grinding after a decade of trial and error.) Let the stones do the work. If you push to much the diamonds will be dislogged from their steel-embedding which is way softer.;) To low angle = low scrapin sound , to high is twitchin not regular sound...)
