Thank you for the information. Quick question. Is this the WWII-era Sako Nobumitsu, or an earlier Nobumitsu? Do you have a reference for the smith?  

[Bruce Pennington]

According to one of the discussions from Ray's link, he worked in WWII

"full mei is Seki Sako Nobumitsu Saku. Not sure how to pronounce Sako...consists of the character SA and MITSU.

Anyway, Sako Nobukazu was a WWII Seki gunto tosho...used the name Nobumitsu. Started in swords there 26 Oct 1939. Nothing else known by me.

Regards,

George." @george trotter

 

And

 

"I believe that the mei reads Seki Sako Nobumitsu saku (関佐光信光作).

Sako (佐光) is family name of Nobumitsu (信光: smith's name), and his real name is Sako Shinichi(reading?) (佐光信一).

Ref. http://www.jp-sword.com/files/seki/gendaito.html

 

BTW, generally 佐光 can also read Sukemitsu when it is used as a given name. @Nobody

 

From Sesko's list:

 

"NOBUMITSU (信光), Shōwa (昭和, 1926-1989), Gifu – “Nobumitsu” (信光), real name Sakō Shin´ichi (佐光信一), born June 24th 1905, student of Kojima Katsumasa (小島勝正), he worked as guntō smith and died July 21st 1993, ryōkō no retsu (Akihide)"

The tsuba is shown upside down and the signature is probably JAKUSHI.
