Buying Guide

Match grit to the task

Use coarse grits (~100–220) for repairing chips and reshaping, medium grits (~1000) for regular edge setting, and extra-fine grits for final polishing

Choose ceramic vs. diamond

Ceramic stones cut predictably and require soaking or lapping, while diamond stones cut faster, need no oil or water, and stay flat longer

Look for portability and form factor

Folding or two-sided stones offer compact storage and multiple grits in one unit for on-the-go sharpening

Check flatness and maintenance

Flat stones preserve consistent bevel angles; diamond plates are low-maintenance, while bench stones may need occasional flattening with a lapping plate

Consider edge use and hardness

Harder steels benefit from diamond abrasives for faster material removal, while softer steels work well with ceramic stones for refined finishes
