MST muller intead japanese

hallo,

Can I use this one MST Müller Water Hone Whetstone Natural Sharpening Stone Razor Hone | eBay to substitute expensive japanese waterstone 8000 grit ?

Thanks

IMO Yes, but youll not get the same edge like using a SuperStone, better look for a coticule.

I'm planing such pyramid :

1. japanese 6000 grit;
2. MST Muller 8000 grit;
3. Chinese natural riverstone 12000 grit.

This will give me nice shave ? It means I plan as final stone chinese 12k, not MST muller.

I guess this could work, but i would save my money for the chinese 12k using a Chromoxid Strop instead, but im a minimalist (Naniwa SuSt 800, several coticules, Celebrated Water Razor Hone & Vintage Thuringian bot around 9-12k) maybe theres someone in the forum that uses the combination youre interested in.

Belgischer Brocken Coticule 125x30mm Messer Leichter Schärfen | eBay

this instead of MST muller ? It's good choice as 8000 grit stone ?

If you are new to honing, go for man made stones.
Natural stones might have flaws and if you get one of those, there is a chance that you will not detect it.
Go for a norton 4/8k or naniwa 3/8k. Also, a good (worn) diamond plate for naturals is a must have, for slurry making, and they cost.
And, keep in mind, generally, what you re paying is what you get. Or something like that. They will do their job, but it will take longer, and, they are not as friendly as the man made ones.
Also, you don't need an 6k and a natural rated at 8k. One is enough for this range. Something in the 3-4k territory could be a better idea.
You can go for a Belgian blue and a Chinese stone, both with slurry stones, but again, the above man made combos are better.

Chinese stones vary a lot I don't recommend it. Same with the MST Muller stone, I have both of these stones as I bought them for cheap probably the same reason you are looking into them. I never use either of them, I only use my NAniwa 1 3 5 8 ss stones and then I move to a coticule or thuringian or other natural stone. IMO don't waste money on naturals until you can get a good shave ready edge from the synthetic stones otherwise when you try out the natural stones if you don't get a good edge you won't know what you are doing wrong or if you just got a bad stone etc.
