Tormek - Bench Grinder - SP-650 Stone Grader
You do not want to be without this double-sided grader.
Use the coarse side regularly to keep the stone open and effective. Also, this will practically get you two grindstones in one. The fine side will change the function of the Tormek grindstone from fast grinding at 220 grit to fine grinding at a 1000 grit surface.
