A medium-grit whetstone around 800–1,200 grit is a useful general starting point for maintaining many ordinary kitchen knives. Very coarse stones remove more metal and are best reserved for damaged edges or specific repairs.
What the grit number means
Lower grit is coarser and removes material faster; higher grit is finer and can refine an established edge. Exact numerical ratings are not perfectly comparable between every abrasive standard or manufacturer.
Start with control and safety
Choose a stable stone with a nonslip holder and follow its soaking or lubrication instructions. Maintain the knife’s intended bevel angle, use measured gentle pressure and keep fingertips away from the path of the edge.
Finish before changing grit
Aim for a consistent edge on the medium stone before moving to a finer stone if needed. Proper burr removal and a stable technique matter more than collecting many grit ratings.
