Hard stones and soft stones

I get question about what is "hard to use" and not hard to use stones:

When i say hard to use its because many many users can not get sharp edge from hard stones because soft stones are coarser and as you know coarser stone gets sharper quicker, but harder stone you have to work on it before you get good edge and you need to know how to use it (with water ,with slurry with little slurry with much slurry) , but with soft stones slurry come very fast and make edge sharp very fast.

Many people think that very hard stones is bad because they do not know how to use them. There is no wonder stones that can make you edge sharp very fast and be extreme fine :)

We talk about very fine stones here so soft stone will be better and finer then any 12k synthetic stone !!
