Tanto dagger signed Yukimitsu

短刀 銘 行光

This record securely identifies a tanto dagger titled “signed Yukimitsu” and explicitly carries National Treasure designation. It does not yet supply the object-level detail needed for a full sword study.

Read the title precisely

The Japanese title includes the term mei, meaning an inscription or signature. “Signed Yukimitsu” preserves that catalogue wording; it should not be expanded into an independently authenticated biography, a school attribution or a manufacturing date. The accepted source fields here do not provide those details.

What a useful next comparison requires

Before comparing this dagger with another sword, obtain an authoritative record for length, curvature, construction, inscription and condition. Comparing only a famous name and legal designation confuses different kinds of information. An editorial checklist is to separate the blade, any mountings and the history of ownership, because a catalogue may describe them at different levels.

Use the identifier, not a guessed story

F-19967 is the Tokyo National Museum collection reference to retain. The blank period and creator fields remain blank in this candidate. No current exhibition, image licence or detailed visual assessment has been verified. The further source research is visibly pending rather than padded with a generic account of Japanese swords.
