27th Generation Kanemoto. An excellent early gendai katana

Katana by 27th Generation Kanemoto in shirasaya with good silver foil habaki.

Nagasa 71.4 cm, 2.36 shaku

Sori 1.58 cm

Motohaba 33 mm   Sakihaba  23.7 mm

Motokasane  8 mm Sakikasane  7mm

This katana has a strong, majestic sugata with a longish chu kissaki, torii zori, a narrow shinogi ji, raised shinogi, and a high irori mune. The ubu nakago is ha agari kuri jiri with one mekugi ana and takanoha yasurime. The blade is signed Niju nana dai Kanemoto and dated Show Kinoe-tora nen Uzuki gatsu kitsu jitsu (Showa 49, April, 1974, an auspicious day)

The steel is forged in a very fine ko-itame and the effect is of fine silver-grey silk. Ji nie occurs, as does the occasional small chikei. The steel is transparent and deep.

The omote starts as a bold sanbonsugi with ashi ire in the valleys and continues to get bolder as it continues into the  monouchi and the peaks begin to reach for the shinogi. Running kinsuji and inazuma leap from peak to peak and detached small clouds of ko nie form above the peaks. The boshi is a continuation of the hamon with a modified jizo turnback and profuse kinsuji.

The ura starts as a fairly regular gunome with hints of togari and sanbonsugi. Ashi in the valleys. The togari and sanbonsugi become more obvious in the monouchi with vertical activity in the peaks. The boshi continues with a modified jizo turnback and running kinsugi. The photos only hint at the activity in the hamon. The blade is in a clear sashi kome polish, and given that the first inch of the ha is unsharpened, probably the original polish.

The following information is rather widely disbursed on the web. I could not find the original source, or I would credit and link to it:

The 27th generation Kanemoto (Hawley KAN 1560/MAG 9; Slough p.44) was born Kaneko Tatsuichiro in Taisho 13 (1925), and was a descendant of the Kanemoto Magoroku school. In 1937 he joined the Nihonto Tanren-sho, where he studied swordsmithing under Watanabe Kanenaga. During WW2 he made swords for the Imperial Japanese Navy and signed Kaneko, Magoroku or Kanemoto. In 1944 he succeeded to the title of the 27th generation of Kanemoto Magoroku, after which he signed "27th generation Kanemoto". He was awarded 20 prizes by Nihon Bijutsu Token Hozon Kyokai (NBTHK) and was officially commended with an award by the mayor of Seki in 1980. He was entitled an Important Intangible Cultural Asset by the Governor of Gifu prefecture in 1997. He died in 24 January 2008.
