This is a very wide and strong wakizashi that is unsigned but attributed to Harima Daijo Shigetaka. In 1992, Yoshikawa Kentaro the founder of the NTHK and his team, attributed this blade to the first generation Shigetaka line of smiths who worked in Echizen Province. The first generation Shigetaka worked around the Keicho Era or 1596 and his style resembles that of the first generation Yasutsugu.
He made mostly wakizashi and this is one of his more robust examples. He is rated as a wazamono grade smith (his blades cut very well). This blade was made during the Keicho Shinto period when it was the fashion to copy shortened Nanbokuchô blades from the 14th century. Even though it is ubu (unshortened), this blade is certainly in the shape of the end of a massive tachi that has been shortened. The hada is typical Echizen hada of mokume with areas of flowing itame having darkish areas. The hamon is a relatively shallow o-gunome-notare that is well done. There are a couple of areas of loose hada in one area (as shown in one of the photos above), but the rest of the blade has a beautiful hada.
The length of this wakizashi is 52.1 cm or 21 1/2 inches. The first 6 inches or so of the blade is an extremely large kissaki. The moto-haba (width at the base) is a full 1.57 inches or 4.0 cm and the width at the kissaki is 1.45 inches or 3.7 cm. This is a very wide and robust blade. The kasane is a thick 0.30 inches or 0.75 cm.
Accompanying this blade is an absolutely outstanding koshirae. It is very unusual to find an old koshirae like this, especially in this kind of wonderful condition. The saya is a fine example of the lacquer artist’s craft. You can see from the photo above the various patterns and designs that have been incorporated into the saya. The tsuba is a Canton style tsuba from Kyushu Province. This tsuba was added later as there is no kozuka ana to allow for the insertion of the O-kozuka which went into the saya at one time in the past. The fuchi and kashira are shakudo done in a mottled style with gold and shakudo designs of seal stamps and gourds. The menuki are very large gilded dragons. All in all, excellent mounts.
As noted above, this blade comes with NTHK papers attesting to the attribution, period, and quality of this blade.
