KME gold diamond grit standard

[Timmyboy]

Hi,

Does anyone know what grit standard (ANSI, CAMI, JIS) the KME gold diamond stones use? Im looking for the equivelent grit stones in the venev diamond lineup.

Thanks

Tim

Tim, I'm pretty new here and to knife sharpening in general, but based on what I've gathered so far, equating the grits won't mean much as the way they're going to perform will be very different. For instance, it seems that the beast 50 grit, the 100 grit, and possibly even the 140 grit stones will cut faster and more aggressively than even the Venev 250/200 micron (60 grit) or 200/160 micron (80 grit) stones will. 250/200 is the coarsest stone Venev currently offers based on what I see on their russian site and others I have checked with my friends over there, but I will list them all for you and give you their equivalents with the help of Gritomatic's chart to get an idea. The purple colored ones are what Gritomatic carries; the others you would have to order from overseas if you can find em. If you're interested in some coarser options that will perform more similar to the Gold Series electroplated stones in a bonded layered option, it sounds like the Poltava metallic bonded CBN may be a good contender, but I've been having some trouble finding much info about them. At their price point, I can totally understand why! Someone else that's tried them would have to chime in to verify if there would be any highly noticeable benefit to them vs the Venevs in higher grit ratings (say, over 400 FEPAish), but I have a gut feeling that it wouldn't justify the 2-4x higher cost per stone.

250/200 (maybe a hair finer than 60 grit on FEPA-F)
200/160 (80 grit FEPA-F)
160/125 (90-95 grit FEPA-F)
100/80 (150 grit FEPA-F)
80/63 (180 grit FEPA-F)
63/50 (220 grit FEPA-F)
50/40 (240 grit FEPA-F)
20/14 (400 grit FEPA-F) (If you're looking at this grit or anything higher than this, you will want to get the yellow OCB bond. The other B2-O1 bond will leave scratches coarser than the grit rating as the binder contains an abrasive component, SiC if I remember right, on top of diamonds ripping out of the substrate)
14/10 (500 grit FEPA-F)
10/7 (600-650 grit FEPA-F)
7/5 (800 grit FEPA-F)
5/3 (1000 grit FEPA-F)
3/2 (1200 grit FEPA-F)
2/1 (~1750grit FEPA-F)
1/0 (2000+ grit FEPA-F)

If I recall his name correctly, Brian from KME answered my question "what is micron for KME diamond plates?", by sending me to the following calculator. This calculator returned: 100 grit or 163μm 140 grit or 118.7μm, 300 = 45 μm/ 57.8, 600 = 30μm, 1500 GRIT = 12.6 μm

Owning first gen Venev bonded diamonds, I can say that the KME'S are all more aggressive cutters grit for grit. For example, Gritomatic's chart reports Venev FEPA-F 150 grit as 90 microns. But the difference in feel to me seems greater then 119 vs 90µ.

Thanks for the responses.
