Blade Description:
A stunning, unsigned katana attributed to Osafune Harumitsu, accompanied by an NBTHK Hozon certificate and mounted in koshirae.
The jigane is a well-forged itame hada with mokume mixed in, of a nice appreciable level. There are areas where the hada is more dense, with mostly itame; there are some stunning parts where the sword shows nice mokume patterns, with thick ji-nie and active chikei.
The hamon is a large notare-based pattern, with ko-nie and nioi forming a slightly subdued but well-controlled temper line (very similar to a wave). Within the hamon, there are ashi, ko-ashi, and yō visible.
The bōshi is straight with a slight hakikake, which returns.
The nakago is suriage. The blade is fitted with a silver habaki featuring a wave motif. The blade is in excellent condition; there are some slight imperfections visible on the images, including some damage to the mune (possibly Homare-kizu?).
Koshirae:
The blade is mounted in a late Edo period han-dachi koshirae.
- Total Length: 94.5 cm
- Tsuka Length: 24 cm
- Saya: Black ishime lacquer with black lacquered horn kojiri
- Fittings: Matching set with nanako-ji and gold edging
- Menuki: Shakudō with plant motif
- Tsuba: Iron mokkō-gata with carved decoration and gold inlay
The koshirae overall is likely a Bakumatsu period piece; the tsuka has been re-wrapped, so it does not preserve the original tsuka-ito. The tsuba is considerably older than the koshirae (in my opinion).
