A Big, Beautiful, and Impressive Katana Bearing A Very Desirable Name & Signature of the ‘Gassan School’

Very long blade measuring a huge 31 inches from Tsuba to Tip. Signed Osaka-ju Gassan Unryûshi Minamoto Sadakazu. With wave design fuchi kashira highlighted with gilt, gilded menuki of gourds. Original Edo lacquer saya. A very nice Koto sukashi tsuba, probably a Choshu school tsuba, with a russetted surface.
It is a very beautiful sword, that is bearing the name of one of the great 19th century sword smith school's, ‘Gassan’, yet we price it for it's own merits and beauty alone, as if it was not actually signed personally, but, it has most intriguing possibilities. A few swords, also bearing his signature name, have appeared in the past fifteen years and sold in the best London auction rooms, but similarly without any guarantee at all as to the authenticity of the smith's personal signature, yet they have still sold for very respectable five figure sums. Thus this is a superbly executed sword, and therefore very possibly a Gassan school homage to a piece bearing his personal name.
It has a stunning hamon that looks tremendously vibrant and impressive, with yakideshi. It has a few small pitting marks at the upper end of the blade, but nothing at all to effect it's use in any way.
This beautiful katana has lain externally untouched as a sleeper for nigh on 100 years or more.
Gassan Sadakazu was born in 1836 in Sugoshi Village in Omi Province. He was the son of Tsukamoto Shichirobei. When he was a young boy, he was adopted into the family of the famous sword maker Gassan Sadayoshi who's only living heir died prematurely.
Gassan Sadayoshi was the founder of the Osaka ‘Gassan school’ of sword making. He studied under Suishinshi Masahide until Masahide's death in 1825. At that time he moved to Osaka and started the revived ‘Gassan school’ of sword making which had died out in the early Edo period.

Sadakazu started studying the art of sword making at about age 11. He made his first sword at age 14 and by age 20 was recognized as a top quality swordsmith and horimono carver.
In the early 1860's when his teacher passed the age of 60, he assumed the role of Daisaku and made swords in his father's name. About this time he produced a number of swords in the Bizen or Yamato style in addition to the main Ayasugi tradition. His blade structure featured a modest curvature and a pronounced large boshi with only a slightly rounded edge (fukura-kareru), which were also characteristic of Sadayoshi's work.
Work stopped for Sadakazu from 1876 when the wearing of swords was abolished until around 1887 when Japan went to war with China and the demand for swords resumed.
He died in 1918 after a long and very distinguished career as one of the premier sword makers of the 19th and 20th centuries.
