Condition & Notes

This antique sword presents a graceful, slightly tapered silhouette with a harmonious gunome-midare temper line and well-defined ko-itame steel. The iron tsuba and classic black lacquer mountings reflect an understated elegance. Free from serious bends, chips, or rust, it shows only minor historic scratches and a pleasing patina. The fittings are tight with no noticeable looseness, making this blade both a beautiful display piece and a reliable tool for Iaido practice and test cutting.
