Jet Wetstone Stone Grader

Almost like magic. A few seconds applying the Grader to the revolving wheel, effectively turns the 250g stone into a much finer grindstone. With the stone changed in this way a much more refined edge is achievable, as the tool's edge will have much reduced grind marks. Once finished, re-apply the Grader using its coarse side and the grindstone is magically transformed back into its original free cutting form.
