The 10 Commandments
of Japanese Steel
A Japanese knife is not just a tool; it is a relationship. Treat it with respect, and it will serve you for a lifetime. Neglect it, and it will fail you when you need it most.
Thou Shalt Not Dishwash
The dishwasher is the death of fine cutlery. The high heat destroys the handle's epoxy, the harsh detergents eat away at the edge, and the water jets bang the blade against other utensils. Hand wash only, immediately after use.
Keep It Dry
Carbon steel (Shirogami/Aogami) will rust in minutes if left wet. Even stainless steel is only "stain-less," not "stain-proof." Wipe your blade dry immediately after washing. For long-term storage, apply a thin layer of Camellia oil (Tsubaki).
Respect the Hardness
Japanese steel is hard (60-65 HRC), which makes it sharp but brittle. Do not twist the blade, pry open cans, or cut through frozen foods, bones, or hard seeds (avocado pits). Use a cleaver for heavy work; use your Japanese knife for precision.
Choose Your Board Wisely
Glass, granite, and ceramic cutting boards are enemies of the edge. They will dull your knife instantly. Use end-grain wood (walnut, maple) or soft rubber (Hasegawa, Asahi) boards that "give" under the blade, preserving sharpness.
No Steel Hones
Never use a ribbed steel honing rod on a Japanese knife. The hard steel will chip against the ridges. If you must hone, use a smooth ceramic rod or a leather strop loaded with compound.
