Naval Tachi

Kai Guntō (海軍刀) Japanese high ranking Japanese Imperial Navy officier

Original unrestored Navy Officier Katana in Tachi Gunto mount


Japanese naval Kai Gunto (Katana) of the type intended for high-ranking officers, Tachi style, the Saya is lined entirely with stripe skin and then lacquered Urushi clear, the blade is of the highest quality among those manufactured in series for naval Katanas, It is made with stainless steel which is then tempered, which is why it shows the tempering line (light Hamon) on the cutting edge. Its parts are numbered with the manufacturing number 834 that appears engraved in the Nakago of the blade (which also has the brand of Arsenal), in Tsuba, Seppas, Fuchi, Tsuka, Koiguchi, Saya, etc. Therefore it is all original and is not restored, shows signs of use and wear but with solid general condition.


Wood Honoki Saya ray skin cover. Great quality arsenal blade with still although very light active Suguha Hamon.

A naval Katana with a tempered blade is really rare because of the difficulty of make a tempering it in steel suitable for the marine environment.  That denotes the special quality of this piece destined without a doubt to a high ranking officer.

Also is very rare matching serial number in blade and all the Koshirae parts at once.
