ka\u014d)<\/p>\n<p>We divide 4 sections for each sword as Saijyo Saku, Jyojyo Saku, Jyo Saku and Regular Saku.<br \/>\nThis work is ranked as Jyojyo Saku among the works of Ikkan-sai Shigetsugu.<\/p>\n<p>Habaki: Gold-covered double habaki<br \/>\nBlade Length: 66.5 cm (26.18 in)<br \/>\nCurvature: 2.0 cm (0.79 in)<br \/>\nMekugi Hole: 2<br \/>\nWidth at Base (Motohaba): 3.04 cm (1.20 in)<br \/>\nWidth at Tip (Sakihaba): 2.11 cm (0.83 in)<br \/>\nThickness of rim (Kasane): 0.62 cm (0.24 in)<br \/>\nSword Weight: 750 g<br \/>\nEra: 1913 (Taisho 2)<br \/>\nShape: The blade has a solid width and thickness.<br \/>\nOn the front side, a dragon and sickle are carved, and on the back side, a sword and dokko (vajra) are carved.<br \/>\nJigane: Well-forged ko-itame hada with a fine texture and excellent quality.<br \/>\nHamon: Nie-based with choji-midare and gunome-midare.<br \/>\nThe boshi is midare and turns back round.<\/p>\n<p>Features: Kasama Ikkan-sai Shigetsugu, real name Kasama Giichi, was a swordsmith born in Shizuoka in 1886 (Meiji 19).<br \/>\nHe was a teacher of Tsukamoto Okimasa and Miyairi Akihira, among others.<br \/>\nHe forged swords at a smithy within the estate of Toyama Mitsuru.<br \/>\nHe received many awards and produced numerous presentation swords.<br \/>\nHe passed away in 1966 (Showa 41) at the age of 80.<\/p>\n<p>Aoi Art\u2019s Comment: This blade features an impressive carving of a dragon, a sword, and a dokko.<br \/>\nThe hamon is also well-crafted.<br \/>\nSword blades with such carvings are rare, and among them, Ikkan-sai Shigetsugu produced many.<br \/>\nAs this blade was made shortly after the Meiji era ended, it can be favorably compared to works by Gassan Sadakazu.<br \/>\nThis is a work expected to gain higher recognition in the future.<\/p>\n<p>Tokubetsu Hozon Token (to be issued soon)<br \/>\nNBTHK Tokubetsu Kicho Token<br \/>\nAoi Art estimation paper: Whole Oshigata<br \/>\n<a
