Venev Bonded Diamond stones for KME/Edge pro & KSPro

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.

That is because the F80 stone is about 185 micron while the beast is well over 300 micron. I is much much more coarse. It is also probably polished a bit from lapping so if you want to rough it up a bit you could give it a pass or 2 from a rougher stone.
 
agreed. however I lapped it on the beast when done so ... there is that too, I can't get any more course than that.

in comparison to the 600 grit diamond from kme, the f80 still felt more fine. I need more stones and more knives to sharpen to really give an opinion.

maybe I lapped the f80 to where its too fine? dunno I don't have enough experience.


what grits should I get? I'm going to order another one this week. 150 240 280 400 600 1200 2000 grit's are the rest of the options. I don't think I should get every one.

the 2000 grit is not fine enough to make a mirror edge from what I've read sofar, but I'm sure there are plenty of finishing stones available to do that.

The Venev stones use the FEPA-F grit scale while most in North America are used to FEPA-P which is very different. The 1,000 Venev stone is around 5,000 grit while the 2,000 Venev stone is around 15,000 grit, or 1 micron in size. That is normally lapping film territory for most people. IIRC green stropping compound is around 3-4 microns in size.

Here is a chart for you to compare http://web.archive.org/web/20151023215953/http://img7.imageshack.us/img7/2636/gritchartrev1.png
 
what scale are the kme diamond stones using then?

the venev are also different in how they are bonded to the backplate. so that changes the way they feel too. the kme you can feel the diamonds scratching, while the venev you can't really feel them, its just feels like flat sand paper ... hard to describe.

I'll order one or two more stones and sharpen another knife some time this month if I get some time.
 
The KME stones are like sand paper. Diamonds are bonded onto a metal plate. This makes them a lot more aggressive than normal stones since the diamonds stick up above everything and have large gaps between them. I am not sure what scale they are using.

The Venev stones are diamonds mixed in with a resin which is applied to the stone. They work more like a traditional stone and they are less aggressive because there is no space between the diamonds.
 
just ordered the 150, 240 and 280 venev stones to add to my 80.

working my way up.

Slight correction. FEPA-F is for bonded abrasives, FEPA-P is for coated abrasives. KME diamonds are coated, venev diamonds are bonded. But 5000 and 15000 are not FEPA-P which has limit 2500 grit. It's japanese waterstone grits (extended JIS) or ANSI for coated abrasives (depending on what is subject).

Thanks for the information!!!
 
Sharpened one knife with the 4 stones. I need to work on my skills, but I like them thus far. Used the beast to reprofile. Got f80 to f280 then I used some lapping films and then stroped it. Worked pretty nicely. Was taking forever to apex this one for some reason, which I didn't have an issue on other's I've done.
 
Well, I just tested my f80 and I find it really outstanding. It's really fast and doesn't scratch the edge as much as the kme stones. I went from there to the 1500 kme grit, then gritomatic black arkansas and stropping. Very good results, almost mirror finish. Gritomatic stones are really good, BTW. I am testing the guangxi, the jasper and the baikalite, and so far, so good!
