Well cut bohi grooves, Iesuke was one of the great makers of the time and into the oei era. Iesuke along with Morimitsu ,Yasumitsu, Moromitsu and Tsuneie who were all leading swordmakers.
His blades are rare to find and very collectible this is an extremely healthy blade and even though suriage has a very good length.
Mounted in excellent Edo period koshirae, the saya is covered in printed Dutch leather which was very expensive and difficult to obtain during the Edo period. All matching fittings on the koshirae from shibuichi which are decorated in a fine katakiri bori design including the Dai seppa on the tsuba the menuki are high quality shakudo and gold. This is an excellent example of edo koshirae custom made to fit this Iesuke katana which would have been carried and used by an active Samurai. Blade is mounted in shirasaya and the koshirae has tsunagi fitted.
