Efficient material removal, for a long time
The SB-250 Blackstone Silicon has sharpening properties equivalent to 220 grit. The SP-650 Stone Grader allows the surface of the stone to be adjusted up to an equivalent of 1000 grit. Its sharp and relatively small grits mean it sharpens efficiently even at low sharpening pressure. This means that the SB-250 Blackstone Silicon holds its shape exceptionally well over time and thus has a very long service life.
