Sword Handle Cap Set (Fuchi-Gashira) of a Badger

This is a fine antique set of matching metal caps (fuchi-gashira) that are at either ends of the handle of the Japanese sword.  The base metal of the set is the copper-gold alloy (shakudō) with a very fine texture.  The set might be made by a goldsmith (kinkō) artist of the Furukawa School in the capital city of Edo sometime during the middle of the Edo Period circa 18th century. They are signed Furukawa Shōju + kaō (古川聖壽「花押」). The design of a badger on a tree is nicely inlayed in gold (kin) and other soft metals in high relief.  This set would be great for collectors as a fine example Edo Kinko style fuchi-gashria or to adore a fine set of matching fittings (koshirae) of a Japanese sword.
