found these available for the KME and edge pro, Venev Industrial Diamonds BONDED DIAMOND STONES.

i was wondering if anyone has tried them yet? i have a KME and would like to try them, but would like to know how well they work first. how would they compare to the standard KME diamond stones?
would the 80 grit be as good as the 50 grit beast from KME? how are the higher grit stones?

they come in 80 150 240 280 400 600 1200 2000 grit's

if anyone has them for other systems im sure they will compare similar to the KME system, so any advice if you have use them would be great. Thank you

i primarly want to use them for fast removal re-profiling. i would assume i have to use something much finer for finishing like the KME lapping film.

Those look very interesting, they look like vitrified diamond stones but they are also very affordable. I'd be interested to hear
 
I'm going to buy a stone next week, I'll let you know.

I have other stones from Venev and they work very well. Be aware that the grit rating on those stones is different (FEPA-F scale) and the 2000 grit stone is actually 1 micron or around 15,000 grit in what you would be used to. 1200 grit is around 2-3 micron IIRC. You can compare the numbers here http://web.archive.org/web/20151023215953/http://img7.imageshack.us/img7/2636/gritchartrev1.png

The diamonds are mixed with a binding agent, some kind of resin for these I think.

How fast do they cut?
 
I think these are the same abrasives that get shipped with the "profile K-02/K-01" sharpening system. If they are, I can say yes, they are good.
 
Thanks guys this is helpful

can you elaborate more on that?

does anyone know what kind of finish do the higher grits give?

and how fast do the low grits remove material?
 
I've heard these may not arrive flat and require lapping.
This from Gritomatic:

Venev Diamonds may have the following minor defects:

Flatness tolerance up to 0.2 mm
These defects will be eliminated during preparation of the stone.

Recommended preparations:

Flattening to remove tolerance.
Making radial bevel for side edges.
Difficulty level: medium.

I don't know what you would use to lap a diamond plate?

that's a good question, does anyone know?
it appears the version that comes with hapstone sharpening system is already lapped, but those stones don't fit the kme. so does anyone know?
 
Very interesting !
I want some for my Edge Pro.
Thank you for posting this question.

As far as flattening what say the experts :

As I understand it if a person took three stones (all of them slightly out of flat) and rubbed them face to face alternating orientations and stone to stone then after a while all three would become flat . . . the errors canceling out the others. I hope that made some king of sense. Meaning I didn't explain clearly why they get more flat.

The advantage would be not harming a diamond stone with fixed grit.

There is a technique like this I have read about in more than one text but fail to find it quickly for this post. One source would be how the Japanese wood worker can produce a VERY straight straight-edge from using three sticks and alternating checking each with the others and planing out the high spots with a woodworking plane or scraper.

Just keep planing the high spots on each, indicated by the others and alternating the orientations of the three each to the other and one arrives at a usable straight edge that is perfectly flat to the ten thousandth of an inch.

PS: I made these straight edges which are EASILY that flat (checked on my Starrett high precision granite surface plate) but I just used the surface plate to find the high spots.

These are ebony and rock maple; used as winding sticks (hence the contrasting colors) among other things.

The lower ones cut fairly quickly

It is the same TYPE of abrasive that you can get with the TS Prof K01/K02 system. They are a diamond and resin mixture bonded to a metal plate. The thickness varies depending on the specific product but is 2-3mm.

They can remove material fairly quickly and wear slowly. Since they are diamond they do not break down but the resin will break down which exposes fresh diamond so they don't give a high polish until the really high grits. I have a 2500 or so stone (7/5 micron) and I can get semi polished shiny edges but they are not mirror polished.

Yes, they will need to be lapped. Since they are a resin bonded stone you can use anything to level them. I used a 220 norton water stone for most of the work and finished on a semi worn 325 DMT plate to finish things off and smooth the finish of the higher grit stones.

You can check out the abrasives in this link. I've only done a couple with the diamonds I find I prefer the stones, but they seem good. Other members really like them.

Thank you.

i noticed a post that mentioned the grit sizes...
esurm said:
The stones are engraved by Venev. Notice how they have F in front of the grit size? That is because they are using the FEPA-F grit scale I believe which is different than the scale used in your list
According to the scale:
200/160 = F80 = 180 microns
100/80 = F150 = 82 microns
50/40 = F240 = 45 microns
20/14 = If F400 = 17 microns
10/7 = If F800 = 6.5 micron
3/2 = F1200 = 3.0 micron = J4000 = ~ANSI 1150 or so,
1/0 = F2000 = 1.20 micron = J8000 = ~Shapton 12000 or so

You can see the equivalents here http://web.archive.org/web/20151023215953/http://img7.imageshack.us/img7/2636/gritchartrev1.png

how would the f80 which is the coarsest grit compare to the beast (50 grit) in the KME diamond lineup? what micron is the beast?
 
so if i want to remove alot of material i should start with the beast, i assume? based on the above information it is a more course grit on the micron scale.

Thanks all this is very helpful. i have a flat granite block, so i should be able to get some course grit and make a slurry to flatten them.

just ordered a beast and an f80, I'll get a few more of the venev in the coming months
 
just received them yesterday. I lapped the venev stone. f80 is there course stone, it felt like a fine in comparison to the beast.

I started with the beast went on to the venev, then 600 grit kme diamond then finished with .5 and then .3 3M lapping films. turned out pretty nice, not mirror finished, but I wasn't going for that.

I'll get more of these in time. they feel different than the kme diamond stones.
 
I just ordered a 400/800 benchstone. I'm very curious

Different in a good way, or in a less efficient at removing material way? I am looking for a budget friendly alternative for the KME stones.
 
well consider the difference in microns, huge difference so the more course beast will remove more material. I don't have enough venev stones to really say ATM since I only got the f80. I like it tho, I need more to make a better comparison. i will say I'm glad I got the beast because the f80 would not work as fast removing material for re profiling.

also I've only just sharpened one knife thus far.
