had the stone to grind my chisel. has recently made me someone with an angle grinder while grinding a notch in the cut. the brown (coarse) page with 1000 grain bears the material very well so that the irregularities are ground out quickly. Finally, ground to the fine side. This polishes the edge to downright. the back (= mirror) several times flat over the fine side pull the burr to remove.
I use the stone in combination with the Veritas Grinding System II and am very satisfied with the grinding results!
