    Comments about ACE HARDWARE Ace® Combination Sharpening Stone:

    Two types of grits for these stones, the black is SiC and the grey is alum. oxide. The grey stone is like 150 coarse side and 300 on the fine. The black stone is 80 grit coarse and 180 fine. I use the coarse black grit stone for rebeveling. It eats up any steel. Then I use the finer side some and on to the fine alum. oxide to further refine the edge. If you can free hand you'll have a very sharp tool. Remember these are entry hardware level stones. Still, good at a very good price.

    It really depends on what you're trying to sharpen. It's all about the sharpening technique and the right stone. I used this stone for clipper blades and boy they hit sharp.
