Here is a stirring Katana from the Wartning States disturbance period dated 1551 (Tenbun 20th) by the famed swordsmith SUKESADA Sθ.
Powerful clans or generals in Warring States Period to the Azuchi Momoyama state required the heavy, massive volume and thick in kasane with high shinogi-ridge holding well-proportioned deep curve. Heavy on hand to form solid durable construction, showing a brave Samurai spirit for practical active use.
Swordsmith SUKESADA Sθ in Bizen Osafune is one of the most distinguished@swordsmiths of the same ranks as KATSUMITSU υ and TADAMITSU υ.
A name of SUKESADA Sθ appeared on Meiou era (1492-). Among SUKESADAs' atelier with the skilled chief with secular names of Hikobei-no-jo FΊqΡ first and Hiko-saemon-no-jo FΆqεΡ then Yoso-saemon-no-jo ^OΆqεΡ did too.
On after latter half of Tenbun era (1540-), starting with Genbei-no-jo ΉΊqΡ, Jiro-Kuro YγY and Hiko-saemon-no-jo FΆqεΡ have been highly celebrated no matter with or without secular name especially the works with date of year during Tenbun (1532-54) generally shows higher skill and upper rank of artistic level than other ages.
The subject sword, although without secular name, uses finer steel with special care in executing, is longer than moderate works to convince that this katana was custom made for the famed general warrior who belonged to a Warlord in the disturbance period.
The truly powerful shape is rather longer than standard holding gracefully deep curve, which is the shape during the transition from Tenbun(1532-54) to Tensho(1573-91) - it stands firmly on wide base, holding abundant volume of Hiraniku, high Shinogi-suji ridge holding well-proportioned deep curvature - entire shape holds awe-inspiring power of elegance in full of brave Samurai spirit. The elaborate made filemarks and courteous chisels of inscription, Nakago remains excellent taste of patina holding an excellent condition over almost 470 yeas history.
This katana has been treasured over hundreds years in really many generations from the middle ages and now presents you the typical workmanship of SUKESADA Sθ.
