Chef-knife maintenance card

Good knife care is mostly ordinary restraint: a suitable board, immediate hand washing, complete drying, protected storage, and sharpening before the edge becomes difficult to restore.

Every use

  • Use end-grain or edge-grain wood, or a suitable soft synthetic board
  • Avoid glass, stone, ceramic plates, bones, frozen food, and twisting cuts
  • Hand wash promptly; never leave the knife in a sink
  • Dry fully from spine to edge and from heel to tip
  • Wipe reactive carbon steel during acidic prep

Storage

  • Use a fitted saya, edge guard, in-drawer organizer, or stable magnetic rack
  • Keep the edge from contacting metal tools or loose drawer contents
  • Store fully dry and away from steam or persistent humidity
  • Use a thin food-safe protective oil for longer carbon-steel storage

Edge care

  • Use a ceramic rod or appropriate strop only for light edge maintenance
  • Do not use a grooved steel on very hard, thin Japanese edges unless the maker recommends it
  • Sharpen when ordinary maintenance no longer restores clean cutting
  • Follow the maker’s bevel and angle guidance; deburr completely
  • Flatten water stones and allow them to dry safely

Stop and inspect

  • Do not continue using a loose handle or visibly cracked blade
  • Small chips need controlled sharpening; large damage needs a professional
  • Remove surface rust gently without erasing geometry or maker marks
  • Never pry, twist, strike, or use the knife as a screwdriver
  • When specifications are unclear, ask the maker before aggressive repair
