Help with sharpening my tools in How Do I Do That? Posted March 15 · Report reply 1 hour ago, Rahere said: Japanese tools need Japanese maintenance. Water stones are far more affordable these days, and shaped slips are available. Keep the wider debate for western tools, please, folks. Different grades of steel. Could you expand on this a bit more? The tools I bought did not come with instructions, so I'm not sure what "Japanese maintenance" encompasses.
