The #120 grit stone is the coarsest in the Shapton Professional range. We have been impressed with it's heavy scratch pattern while staying relatively flat for such a coarse stone.
As with the rest of the Shapton Professional range, the #120 is manufactured to maintain flatness for a relatively long time. For best results, we recommend regular light flattening of the stone with either a diamond plate or sandpaper on glass.
From the #120, we recommend thorough work on a #220 or #320 stone, as the jump to the #1000 will require a fair amount of work to remove the heavier scratches of the #120.
Stone size: 210mm x 70mm x 16mm
