May I ask stupid question of why would you want natural coarse stone instead of synthetic? Just because it's natural and fits nicely into your collection of naturals?
I'm asking because I have a very pragmatic position regarding stones: they are just tools for keeping knives sharp. And from this point of view it seems quite strange to spend lots of cash on natural coarse stone that can't compete in price/effectiveness to synthetic stones.
Probably I'm missing something. For example there's a nice JNS 300 synthetic stone. What natural stone could compete with it? By competing I means it should remove steel in similar speed and should cost somewhere around 90$ (which is JNS 300 stone price at the moment).
Are there naturals that could compete with JNS 800 synthetic?
Feed me with some links please
