I’m looking for thoughts from this expert company on a mumei wakizashi that I just purchased from Japan. I am a complete beginner in nihonto, although I have some limited background in smithing, casting, etc I picked this nihonto because it looked like it was in “working class” (if such a thing can be said about nihonto) koshirae, in the tachi style.
Sugata:
Nagasa – 54cm
Motohaba - 29mm, Sakihaba 18mm
Motgasane - 5mm, Sakigasane 3.5mm
Sori - 10mm
Mune – Iori-mune
Kissaki is chu-kissaki, but on the o-kissaki side, with a fukura on the scarce side of medium.
Blade is in a decent sashikomi polish – better than expected, but with some scratches and defects
This blade appears o-suriage (tensho-suriage). Although the polish makes it look like the hamon ends in the normal way, beneath the polish it appears to continue into the nakago. If there was a mei, it was lost.
Tsuba is copper, in a simple wave pattern, with the mei on the blade side. Tsuba appears to have originally been fitted to a tachi, with the nakago-ana later inverted. Tsuba mei is “Shoami”, but with an unusual variant of the simplified character for “mi”. I can’t tell if the hitsu-ana were original, or added later. Without the signature I would have called it probably ko-kinko… I wonder if it is possible that it was signed by the smith doing the conversion? Tsuba fit is quite loose.
Saya appears to be wrapped with a course fabric and lacquered with possibly a vermillion lacquer, and has Ishizuki and Kashiwaba. There is no provision for a kuzuka or kogai.
Fittings are all workmanlike rather than fancy. Menuki is a nice running boar (in shakudo?)
As to the blade, here my extreme lack of experience means that I may be way off track. My thoughts:
Jigane & Jihada
Itame mixed with mokume, only visible in some areas beneath the sashikomi polish. Distinct ha-hada. No evidence of Chikei.
Hamon & Boshi
Hamon is gunome-midare, tending towards koshi no hiraita. Fairly bright nioiguchi, with nie in both the ha and ji, and islands of nioi/nie in the ha. One area of distinct midari utsuri, but otherwise absent or not visible. There are dark lines cutting through the nioi/nie – part of the forging structure, but not distinct kinsugi.
Kissaki boshi is Notare-komi, tending toward Kaen.
When and where?
My wild guesses as to date/area: If this is the lower half to two thirds of a tachi, as I guess, the slender form and taper feels Heian, but the hamon more early to mid Muromachi (Oei Bizen?). I’m guessing that the sword broke, and the length remaining was only sufficient for a wakizashi length blade. Possibly the saya was also shortened, keeping the original tachi fittings. These fittings could also be bakamatsu, but the style and simplicity makes me think not, and the O-suriage appears to have occurred a long time ago, given nakago condition.
I look forward to your thoughts
