Whetstone

Every edge goes dull, and a dull blade is the dangerous one. A whetstone brings it back while taking the least metal, so one good knife lasts a lifetime instead of a season.

Which grit
Coarse (~400)Repairs chips and reshapes a badly dull edge. Leave it alone until your technique is solid.
Medium (1000)Sets and sharpens a normally kept edge. The side you reach for most.
Fine (3000–6000)Hones and polishes, takes off the burr, leaves a clean keen edge.
Extra-fine (8000+)A mirror finish for fine kitchen and Japanese blades.
Strengths
Removes the least metal, the blade lasts
You set the angle, not a fixed slot
One stone, every blade you own

Watch For
  • Skip the pull-through carbide sharpener; it grinds at a fixed angle and tears metal off, so it works for a day and shortens the blade for good.

  • Keep the stone wet the whole time, soaking the coarse side first; a dry stone clogs and scratches instead of cutting.

  • Flatten it when it dishes, with a flattening stone or wet-dry paper on glass; a hollowed stone rounds the edge instead of sharpening it.

  • Hold one steady angle, around 15 to 20 degrees; wobble rounds the edge, and a guide clip helps until the muscle memory sets in.
