Fine- Restores to a fine edge any knife or tool that is slightly dull. Many of our customers consider the fine grit to be a medium/all purpose sharpener. Professional Chefs and gourmet cooks prefer using our fine grit models. For woodworkers and sportsman who are stepping through the grits, it’s the edge refinement step done before micro beveling and polishing. Diamond size: 25 micron /  600 mesh

Extra Fine- Refines and polishes the sharp edge to razor sharp perfection. If you are new to sharpening or if you do not need your knife or tool edge to be as sharp as absolutely possible, this grit is not recommended. But if it’s not sharp until it’s sharp enough for you, this is the grit you are looking for! Diamond size:  9 micron /  1200 mesh.
