Description

This is a tanto made by Kasai Sanenobu, a matchlock gunsmith from Awa Province, dated Koka 4 (1847). It is accompanied by an NBTHK Hozon Token certificate. The blade is housed in a shirasaya.

Historical context

Under the Tokugawa peace the daishō became a regulated uniform, and demand gathered in the castle towns, above all Edo itself. The craft split two ways: brilliant display work for connoisseurs, and tested blades whose cutting results were sometimes inlaid in gold.
