TANTO with KOSHIRAE
The Shodai or first
generation Soshu Masahiro was said to have been a pupil of Masamune.
While certainly not that Masahiro and, due to a number of Soshu
smiths using the Masahiro name, as well as their works being
it is difficult to pinpoint the exact generation which made this
Tanto, hence the "Den" or school attribution by the NBTHK.
Fujishiro had this to say, "Most Soshu Masahiro blades are
forgeries, and genuine blades are rare"
As this sword is accompanied by papers from the NBTHK, I suppose we
will consider it rare!
This Tanto has seen a few polishes in it's 400 + years of existence,
but overall it is still in really good condition and quite enjoyable
There are a few small areas of light scuffs, hike kizu or surface
scratches, kitte ware, etc., but nothing at all serious or much less
The overall sugata of this Tanto would suggest later Soshu work,
perhaps Odawara Soshu, and most likely Muramachi period.
The ji-hada is hard and very tightly formed, with a few areas of
mokume which is characteristically coarse.
The hamon is hitatasura which consists of nioi and ko-nie.
There is an abundance of activity to be seen such as ji-nie,
hakikake, sunagashi, uchinoke, tobiyaki, inazuma, nijuba, etc..
The Aikuchi style Koshirae
is done in a dark brown lacquer with gold lacquer and crushed
abalone shell inlays representing water and gold
lacquer of a goose and the moon, though the inlay in the moon is
The kurigata is iron with gold scroll work.
The Koshirae comes with custom tsunagi.
The Shirasaya is well above average and features Horn koiguchi and
fuchi as well as ivory Hatome.
