if it is much slower then a norton 8k (i dont know its relative speed) would you still use it between the 4k and 8k?

What I want to know is if it is primarily a type of quartz and consequently the effective grit is determined by the grit of the lapping medium.
I like these stones and have 2 of them. The first one I bought was for my scythe and is a canoe shaped scythe stone. I have to say that is for the Austrian scythe and not the heavier English Scythe which is sharpened with a coarser stone. I then bought a small bench stone for woodworking. This stone is said to be the king of axe sharpening stones and will give the perfect finish for an axe, indeed a finish that you can shave from. I have seen pictures and videos of people shaving with an axe, something that I will not be doing any time soon.
I like the stone and it is very hard and cuts well with average speed. Not sure exactly what grit it is but 6000 grit is its upper limit IMHO
For those that care about reading ancient threads.
"The Rozsutec gets increasingly finer after intensive use,
probably due to the very hard bond causing the grains
hardly wear or get loose particles. Dressing goes very well
by using a natural Japanese Nagura stone. This smells
strong, but works very well. It creates a slurry that makes
the grinding with the Rozsutec stone much faster. The
slurry gets fairly rapidly much finer."
And just for your info:
Originally the sandstone is blue, but by corrosion the
surfaces, of the plates, the sandstone turns brown.
Therefore, almost all Roszutec whetstones have 2 brown
edges and a blue center band.
These are still being mined by one family in Slovakia
Cheers....
P.S. This is a very versatile stone hone.
