Shakudo kozuka signed "Omori Hidehiko". Signature looks perfect compared to the example in "Toso Kodogu Meiji Taikei". His name could also be read as Teruhiko. He was a student of both Teruhide and Terumitsu. Active in early 19th century.
This kozuka does not look good in the dark, however it comes to live under strong light.
Made in late edo period.
