Description

This is a shibuichi kozuka signed "Joi", though the signature is considered gimei (false) compared to confirmed examples of Nara Sansaku Joi. Despite this, the quality of the carved faces is notable, featuring inlay made of two separate color gold alloys. It is an Edo period piece.

Warning — certificate not found

We could not find an authenticity certificate on the seller’s listing. Japanese swords and fittings are normally papered by the NBTHK (or the NTHK). Without one, the attribution is the seller’s own assessment and has not been independently verified — treat it with caution and ask the dealer about certification before buying.
