After all too many years of hand sharpening blades...

I found I now use my large diamond stones (120, 220, coarse, fine, 8000 - 3 micron) for almost all my work. My expensive wet stones and ceramics sit there gathering dust as these diamond stones put out razor-sharp edges with minimum clean-up and maintenance...

And in the field, I find myself armed with an EZ-Lap Diamond Rod and a small ceramic rod that I cut down to 3" and use like my leather strop at home. I even have a diamond (credit card sized) fine grit in my wallet that sees some use when I wearing non-jeans clothing...

Is it just me or have others of you gone "Diamonds Are Forever?" :confused:
 
Yes - Diamonds are man best friend. I use DMT 120 grid D8XX + D11C + D11E and then Green Rouge on thin leather (non Hand American) to bring my knives to hair whittling sharpness.

Thanks, Vassili.
 
Yup for all my coarse work, anything under 1000 grit, I now use diamond. For 1000 and higher I use water stones, and prefer them over any diamond . Heck for the finer grits I even prefer ceramic over diamond. A really great quick touchup hone is the Spyderco Doublestuff, med/fine on a very handy size hone.
 
Ditto. After many years of using various types of whetstones, and even a Lansky for a while, I have recently purchased a set of DMT hones, and I absolutly love them. I may never go back to the stones. At least not the coarse ones, anyway.
 
I like the DMT diamond hones, but i find they lose their "cut" rather quickly and turn smooth (even after flushing and scrubbing with a toothbrush to remove the slag). So my extra coarse DMT is now a "fine grit" DMT, and my extra fine DMT is now a "superfine" DMT.

any diamond stones out there that DONT lose their "cut" like the DMT's?

:(

How long do you use it? They are coarse at the beginning and after few sharpening came to normal grit. I sharpen for quite a while and so far they still able to sharpen pretty good.

Thanks, Vassili.

Maybe you're bearing down too hard? Let the stone do the work.

I'm interested in what you consider "large". I recently got a couple of DMT 8" stones which seem much easier to use on larger knives than 6" stones. Now I'm wondering if a 10" would be worth the investment.

Would be interested in the answer to this from anyone following this thread.

:cool:
 
Interesting, about the success stories versus the dulling stories... I was just planning on getting some new diamond hones, despite having significant dulling issues with my XCourse DMT stone.

They have 11+" and it does worse it, because you may sharpen entire edge in one move. They are 2+" wide - thinner then D8 and cost the same as I understand.

Thanks, Vassili.

Hi,

Have a read of what Edge Pro has to say on diamond laps lasting:

This is what I read there:

"The last diamond we tested was a DMT Industrial Super Coarse, it lasted for 10 knives and it was completely smooth and it never came close to cutting as fast as our coarse."

It is absolutely different from what I experienced! It is so different that it is really hard to believe! I did re-profile more then 10 knives for sure - this is really heavy use, probably more then average customer will experienced in less then 6 monthes!

Here list of knives I reprofiled with my DMT D8XX - Extra Extra Coarse. And I use Corse and Extra Fine without any sign of wearing out, but D8XX was use really heavy and eat quite a bit of steel.

CRTK Apache I - ATS34 - removing serration (it takes 15 minutes BTW)
CRTK Apache III - ATS34 - removing serration.
Spyderco Endura ZDP 189
Spyderco Delica ZDP 189
Zero Tolerance - CPM S30V
4 x Busse Game wardens - INFI - very thick edge reprofile them from 40 degree to 30
2 x Busse Active Duty - INFI - thick edge reprofiled to 30
2 x Busse Badger Attack - INFI - thick edge reprofiled to 30
2 x Busse Meaner Street - INFI - thick edge reprofiled to 30
Swamp Rat HRLM - SR101 - thick edge reprofiled to 30
Swamp Rat Ratmandu - SR101 ...
2 x Laury PT (63HRC) - UHB17va
Laury Leuku - UHB17va
2 x M.Calldwell - 154CM
Spyderco Military - CPM 440V
Spyderco Military - CPM S30V
Spyderco Military - BG-42
Cold Steel ODA - 420HC
Buck Strider Solution 888 - ATS34
Marychev Chirok - 95x18

...So total is 28 and no sign of wear out - it continue to eat steel as a beast. Initially it was as a belt sander but in one-two knives it turns from belt sander to just Extra Extra coarse.

This is my main solution for reprofiling - very effective.

This is just a prove that it work on more then 10 - on 28 knives and it is far from limit - I am continue to use it with great success!

Thanks, Vassili.

+1 The diamond hones work very well on harder steels like D2. If you try to hone soft steel with a diamond sharpener, the soft steel will pull out the individual pieces of diamond.

I am not sure - to me INFI - 58HRC is relatively soft and I never experienced effect you are talking about after re-profiling 10 Busse knives (see my previous post). As well as on 420HC from ColdSteel.

Thanks, Vassili.
 
I have rebevelled countless knives with my DMT D8XX, from ZDP 189 to VG-10 to ATS-34 to S30V, ect., and it still devours steel with no signs of wearing out. I use huge amounts of pressure, too, and it eats steel extremely quick. I couldn't recommend this stone more for rebevelling.

Alright, given all this... does anybody have any suggestions on where to buy a DMT Magna-Guide? Or should I start my own thread?

If they have such a grate amount of diamonds worn out may be you should not use any guiding system at all. According to this report it seems like very idea have something to do with stones being dulled after relatively small load - 10 knives with soft steel is just nothing to diamonds and if it is related to method which was used, I rather avoid it.

Thanks, Vassili.
 
Hi,

This has come up before. Seems like too much presure is the cuase

http://www.bladeforums.com/forums/archive/index.php/t-244307.html

I had the same expirience as in this tread: - I wore out a coarse stone reprofiling one 440 bladed knife. Granted I had to do alot of honing, but it was one knife, not 10.

Here is another http://www.gunandgame.com/forums/knives-cutlery/39574-re-dressing-lansky-diamond-hones.html

And Joe Talmage thinks they wear fast

http://www.candlepowerforums.com/vb/archive/index.php/t-147776.html

Not everbody agrees that they last for ever

To me this is not matter of consensus. I use mine a lot and it was not worn out. Same for gunmike1.

At that links:
Joe Talmage did talk about Spyderco sharpmaker diamond rods
Deep13 did talk about Lanski diamonds.
Bushman5 did talk about DMT but pocket sharpeners I think it is too small for reprofiling - I think they are more for touch up in the field and so base may be too weak for 9 hours of reprofiling - I am not familier with this model. I doubt that any extra coarse pocket sharpening device will stand 9 hours of reprofiling.

To me based on this you can not speak for all diamonds.

I have D8XX - DMT main battle beast - Extra Extra coarse 8"x3" plate and it worse every penny. As I sad it works almost as belt-sander without noise, without dust, without possibility of injury, much more precise and it wear out much much less then any other sharpening tool especially at this grid.

I think that it is also may be related to monocrystaline diamonds they use. Policrystaline - smaller diamonds burned together to form bigger abrasive grains may separates from each other under pressure, while DMT claim to use solid abrasive grains.

Thanks, Vassili.
 
I used my DMT Extra Coarse to reprofile my SOG Seal Tech bowie. Just the one knife and it is uber smooth (the extra coarse now feels like my DMT Fine diamond hone)

It certainly did not devour the steel on the blade, barely scratched it without pressure.

The Extra Coarse (i bought a new one) RIPPPPPED thru the steel in my meat cleaver (plain ol carbon steel). After shaping the bevel the DMT still felt rough like when it was new.
