Listing for sale an interesting Hizen-to katana in koshirae. The sword is 27.4" and is suriage with only a partial mei remaining "Hizen (no) kuni ju". The sword is not papered and will need to go to shinsa to verify which smith this is. I have however shared photos with Roger Robertshaw to get his thoughts and he felt it was definitely a work by the nidai Tadahiro (Omi Daijo) circa 1633 and referred me to page 108 of his book. He also felt that the nijuba which could be seen in the photos reinforced that attribution.
The sword is an exceptional piece of work. The nioi-guchi is very wide and bright, and the hamon is lined with prominent ashi. The sugata is wide and powerful. The jitetsu is a typical one for this smith, a tight and beautiful konuka-hada with some strong chikei towards the habaki-moto. There is a short kitae-ware on the mune near the habaki which I will photograph.
The Tadahiro is in koshirae only, no shirasaya. The menuki *may* be solid gold. The tsuba is exceptional I feel, but I cannot personally give an attribution (open to thoughts here). Both seppa are gold foil with no tears. The kashira is tsuno (horn).
