04 / Research & provenance

RESEARCH NOTES

  1. 01

    登録 (Tōroku) means “registered”; it is not a smith’s name.

  2. 02

    The Japanese Honmamon catalogue lists 源光金; its English version uses Minamoto Mitsukane.

  3. 03

    Specifications of current knives under the same brand do not establish this piece’s exact steel, construction or age.

PROVENANCE

The owner supplied the 430/300 mm dimensions, 281 g weight, carbon steel, double bevel, original handle and cleaning-only treatment. Earlier ownership, manufacturing location and exact age are undocumented.
