TSProf with KME Stones?

[wade7575]

How do you compare these to the Diamond matrix stones? I have the Venev currently as I got a good deal purchasing them together with EP Apex, but curious about the Diamond matrix as well as their metallic bonded cbn.

I prefer the Venev stones myself and I have gotten great result's with them for sure and I use Bar Keepers Friend powder in the gold canister to clean them off.

I’ve used Venev and Matrix stones and liked the Matrix better for feel results and cleaning. Wade has tried both and likes the Venev better so it sounds like personal preference thing, Ford vs Chevy....
Metallic bond stones don’t seem to last well at all, but with any brand of diamond stone the secret is sin a light touch or easy stroke, don’t lean into it, the softer the better actually.

The Poltava Metallic Bond CBN stones do not have any problem at all with wear,the only thing most people don't like about them is the need to refresh them every so often.

^Would be interesting to see a side-by-side comparison of the metallic CBN, vs the diamond matrix, vs the Venevs, on things like: maintenance (how OFTEN does refreshing of the stones need to be done for frequent sharpeners), cutting aggression (how quickly can the lowest 1 or 2 grit stones in each series do a common task like reprofile a factory bevel from 20 to 15 dps), and edge performance (after working through a standard progression of 3 to 4 grits prior to stropping, what does the edge look like, and cut like, on common sharpness tests).
