Katana in Military Sword Koshirae (Gunto Koshirae)<\/p>\n

Signature: Mumei (Unsigned)
\n\u7121\u9298<\/p>\n

(We divide 4 sections for each sword as Saijyo Saku, Jyojyo Saku, Jyo Saku and Regular Saku).
\nThis blade is ranked as Regular Saku among unsigned works.<\/p>\n

Habaki:
\nBlade Length: 2 shaku 2 sun 2 bu, approximately 67.27 cm (26.48 in).
\nCurvature: 6 bu, approximately 1.82 cm (0.72 in).
\nMekugi Hole: 1.
\nWidth at Base (Motohaba): 3.03 cm (1.19 in).
\nWidth at Yokote: 2.10 cm (0.83 in).
\nThickness of rim (Kasane): 0.60 cm (0.24 in).
\nSword Weight: 760 g.<\/p>\n

Era: Showa period, during World War II (1939\u20131945).<\/p>\n

Shape: A robust katana with a wide mihaba, substantial kasane, and an elongated kissaki.<\/p>\n

Jigane: The forging appears to be somewhat insufficient, and we believe this blade is a partially forged sword, commonly referred to as a Han-Tanren-to.<\/p>\n

Hamon: Nioi-deki gunome-midare.
\nThe boshi forms a rounded tip with a turnback.<\/p>\n

Features: Generally, non-traditionally forged swords (Mu-Tanren-to) bear markings such as the Showa stamp, Seki stamp, or anchor mark, indicating their classification as non-traditionally forged swords.
\nHowever, swords bearing the anchor mark were forged, so we believe they may qualify for registration in Japan.<\/p>\n

Other types of non-traditionally forged swords are subject to confiscation during the registration examination.
\nSimilarly, Mantetsu-to swords manufactured in Manchuria are not eligible for registration in Japan.<\/p>\n

Koshirae: Imperial Japanese Army Gunto Koshirae.<\/p>\n

Aoi Art\u2019s Comment: Regarding Japanese swords produced during World War II.<\/p>\n

During the war, some officers and non-commissioned officers in the Japanese military carried Japanese swords.
\nMost Japanese Army swords survived the war, but relatively few Japanese Navy swords remain today because so many naval vessels were sunk.<\/p>\n

War is a cruel tragedy that separates countless families and takes the lives of many people.
\nWe sincerely hope that humanity will firmly resolve never to allow such a war to happen again.<\/p>\n
