Antique Japanese Sword Shirasaya Katana Unsigned Kanemoto with NBTHK Kanteisho Certificate

【Description】

Masatoshi (正利) was a swordsmith from Mino province in the late Muromachi period(1532-1558). He was a son of Sakakura Masayoshi. He forged swords in the Sakakura town near Seki city(the central area in the Mino province), so he was also called Sakura Seki swordsmith. It is said that he had a technological exchange with Muramasa school, a prestigious sword-making school back then. The signature of Masa(正) made by Masatusgu resembles that of Masa(正) made by Muramasa(村正) to support this reasoning.

The MINO swordsmiths style, also known as MINO-DEN, basically has the TOGARI(Pointed shapes protruding from the Hamon )in a classic straight line and random temper line with some white Utsuri. MINO-DEN had its origin from YAMATO-DEN in the late KAMAKURA period(1280-1330). It flourished in the MUROMACHI period(1333-1573) and continued until the EDO period(1603-1868).

MINO-DEN especially prospered during Sengoku Jidai(Warring State period) due to the high demand for weapons. And the location of Mino province beat others. Akechi Mitsuhide controlled Mino province, and Nobunaga Oda ruled Owari province, and Tokugawa Ieyasu was the lord of Suruga (Neighboring areas). There was high demand from those powerful feudal lords and their retainers. Furthermore, so many wars occurred between the Kanto region and the Kyoto area, and Mino is located in the middle, making feudal lords feel convenient to order swords from MINO-DEN. The blades forged in MINO provinces also had the reputation of their practical design and sharpness. Many feudal lords demanded swords forged in the Mino province.

This blade has beautiful Jihada, and the shape of Kissaki(tip part) looks very strong. It is rare to find such a long blade(73 cm) made in the late Muromachi period because most of the swords forged in this era were shortened due to the size adjustment in the Edo period.

【Blade 】
Cutting Edge Length(Nagasa) 73 cm(28.74 inches)
Curvature(Sori)1.96 cm( 0.77 inches)

Hamon
The crystalline structure which forms along the cutting edge of a blade as a result of the hardening process
Jimon(Jihada)
visible steel surface pattern created by folding and hammering during forging process


【Other details】

NakagoNakago is the hilt of the Japanese sword.

This blade was shortened at least once based on the number of holes on the tang. Japanese swordsmiths left the black rust on the tang because it prevents red rust while the tang is in its handle. And the discoloration of the tang was created over time, and it is a great indicator for a Japanese sword specialist to estimate when the sword was forged.

 

Habaki Habaki is the equipment to make the blade not touch its scabbard inside. It prevents the blade from getting rusty and chipped.
