This answer is a draft. It stays unpublished until legal review and source verification are complete.
Separately from our article on sharpening, this one answers the safety questions: "isn't a sharp knife dangerous?", "how should I store it?", "when can a child start using one?". It draws on the kinds of knife found in Japanese homes and on accident data from the Consumer Affairs Agency, and includes a note on Japan's knife-carrying law.
| Item | Detail |
|---|---|
| Sharpness and safety | A dull knife needs force and slips, cutting your hand. A sharp knife needs little force and is easier to control |
| Grip | Hold the handle; do not rest your index finger along the spine of the blade (in ordinary homes, a plain handle grip). The other hand is the "cat's paw" (neko no te, 猫の手): fingers curled, holding the food with the first knuckles |
| Cutting board | A stable surface; a damp cloth underneath stops it sliding. The right height is one where the tip of the blade reaches the board with your arm extended |
| Washing | Straight after use, blade pointing away from you, sponge working from the spine side. Never leave it in the sink (the classic accident: cutting your hand on a blade you cannot see) |
| Drying and storage | Wipe and dry straight away (rust). Cover the blade (knife block, sheath; on a magnetic strip, never with the edge facing out). Do not put it loose in a drawer |
| Children | From the early years of primary school (about age 6–8), with an adult alongside. Start with a children's knife (rounded tip). Teach the "cat's paw" first |
| Types | Santoku (all-purpose), nakiri (vegetables), deba (fish), yanagiba (sashimi), petty (small utility). Stainless steel resists rust; carbon steel (hagane) cuts better but rusts |
| Disposal | Wrap the blade in newspaper, write the word for "blade" (刃物, hamono) on it, and put it out with your municipality's non-burnable or hazardous waste |
[Verify] Check the accident data against Consumer Affairs Agency materials, and the provisions of the Firearms and Swords Control Act against National Police Agency materials.
The opposite. Force, then a slip is the pattern of accidents. Sharpen regularly (see our sharpening article).
The classic accident: cutting your hand on a blade you cannot see. Wash and dry it straight after use.
From the early years of primary school, with an adult watching and a children's knife. The "cat's paw" first. Japanese food education holds that a child never allowed to touch a knife becomes an adult who does not know how to handle one.
Mounting it so the edge is exposed and faces outward is dangerous. Edge towards the wall, at a height children cannot reach. Homes with children: a knife block with a door.
Wrap it thickly in newspaper, write the words for "blade" (刃物) and "danger" (キケン) on it, and put it out with your municipality's sorted waste. This is a shared rule in Japan to protect the people who collect the rubbish from injury.
