Special feature: First generation Yasutsugu was born at Oumi province
and moved to Echizen province. Tokugawa Shogun’s order,
he made swords for this Syogun Ieyasu.
He was permitted to cut the Aoi moon(family crest of Aoi Tokugawa family
and also received the name of Yasu(one of the charatoer of Tokugawa Ietasu)
This sword is 3rd generation Yasutugu which was made at Echizen province.
For making swords, Yasutsugu used Nanbantetsu(western steal
which was made at Holland ) which was very precious.
I think he made swords mixed with western steal and Japanese Tamahagane.
Nanbantetsu is not clear jigane and dark deep gray color
but cut well sword after mixed with Japanese Tamahagane.
The price is quite reasonable. We recommend this sword.
