Does nothing
The stone itself starts to break down when i sharpen my knife, and eventually does nothing, waste of money

Not much good. Or may i don't know how to use as I'm not be able to sharp my knives.

kind of works
they should write a disclaimer, as this CAN NOT make blunt knives sharp, but I would still give it a 4 star review because it CAN make already sharp knives even sharper, which is what I needed

Useless
Showing on the pictures and on product informations that the stone has 2 different sides with 2 grinding numbers. In reality it's only one number from both sides
