Long Sword (Katana) by Kunitsuna
This is an antique long sword (katana) by the master swordsmith Kunitsuna who worked in the castle town of Fukui in Echizen Province between the Keian Era and Manji Era (1648-1661 CE). The temper pattern (hamon) resembles small regular bunches of cloves (chōji) composed of whitish invisible martensite crystals (nioi). Areas above the temper pattern are regular small patches of harden steel (tobiyaki). This is visible in third and fourth photograph for reference. Overall the sword shows a strong influence of Sōshū tradition. The healthy unaltered shape of this long sword has a ridgeline on both sides of the blade and a defined tip (shinogi-zukuri).
Based on the characteristics of signature, workmanship, and comparing it to other authenticated examples of this swordsmith's work I guarantee the authenticity of the signature if submitted to the NBTHK (Society for the Preservation of the Japanese Art Sword) for appraisal.
The sword is signed on one side (Sagami Kami Fujiwara Kunitsuna 相模守藤原國綱) the title and name of the swordsmith. On the other side is inscribed (Echizen Ju 越前住) meaning the swordsmith was resident of Echizen Province. The antique long sword comes in a plain wooden scabbard (shira-saya). It also has a very nice silver foil one-piece copper blade collar (habaki). The cutting-edge length (nagasa) of this long sword is 71.2 cm (28.0 inches). The overall length is 97.5 cm (39.0 inches). The condition of the sword is excellent for its age with a few minor nicks to the blade collar on one side.
