Features: This is an o-suriage (greatly shortened), unsigned katana attributed to Yamato-Shizu.
\nThe term Yamato-Shizu is said to refer either to works made while Kaneuji was still forging swords in Yamato, before he studied under Masamune of Soshu, or to a separate group of smiths who remained in Yamato after Kaneuji had studied under Masamune, attained mastery, and settled in Mino as Mino-Shizu.
\nIts appraisal is therefore exceedingly difficult, but\u2014as can be seen in this sword\u2014the name is given to works that appear to be by the same Shizu school yet retain abundant elements of the Yamato tradition.
\nIts production dates from the late Kamakura to the early Nanbokucho period, and it fully displays the characteristics of the Yamato den.<\/p>\n

Aoi Art’s Comment: A certain renowned sword appraiser once asked me which of the two is superior and which inferior, Yamato-Shizu or Naoe-Shizu.
\nHe said that Yamato-Shizu is the more fitting.
\nSince then, I have observed them with care.
\nI believe Yamato-Shizu has the trait of an unexpectedly deep hamon, whereas Naoe-Shizu tends to show a broader hamon.
\nI feel that Yamato-Shizu captures the Yamato character especially well.
\nLooking at numerous Juyo Token, one comes to understand clearly why such blades are judged to be Yamato.
\nI consider Yamato-Shizu to be older in date than Naoe-Shizu, and I also regard its jigane as fine.<\/p>\n

Historical Background: The late Kamakura period (the latter half of the 13th century to 1333) was a turbulent age marked by the economic distress of the gokenin (vassals) brought on by the successive Mongol invasions (Genko), and by the political corruption that advanced under the autocracy of the Hojo clan (the Tokuso despotism).
\nIt refers to the period of upheaval during which discontented samurai and the imperial court rose in arms, culminating in the fall of the Kamakura shogunate in 1333.<\/p>\n
