無銘(近景)

Features: Chikakage was a swordsmith of the Osafune school in Bizen Province during the late Kamakura period.
He was a disciple of Nagamitsu, and some works of Kagemitsu (son of Nagamitsu) bear inscriptions nearly identical to Chikakage.
His style resembles Kagemitsu, but closer examination reveals stronger nie, a prominently expressed Sanko-boshi, and a more pointed boshi, showing unique characteristics.
This blade is exceptionally wide, with bohi carvings on both sides, and presents a dynamic form with ikubi-kissaki style.
It is designated as a Tokubetsu Juyo Token.
The jigane is superb, tightly forged with well-visible utsuri throughout.
The utsuri is vivid and forms midare-utsuri patterns.
