    @Bruce Pennington    my understanding with both NA and KO stamps: 

     Na / Ho (名/ホ): externally made blades collected by Nagoya inspectors, then delivered to Kokura Arsenal, and “processed” presumably polished, in Factory No.1.  Often sent elsewhere for mounting.  This stamp combination started late 1941, peaked in 1942, and declined in 1943 and not seen in 1944.

    Thanks, Mal.  Thought it was something like that.  And you beat me to the punch on the mune stamp practice peaking in 1942.  I checked my charts to see if it was used predominantly on star-stamped blades, but they were found on non-star blades and Seki stamped blades just as often.

    Hi Bruce,

     

    This one is interesting because it has two distinct and elaborately done kanji on the spine of the tang. They are not arsenal marks. Not something I see every day. (Especially for $500 USD.) People discard things, so sad.

    I would truly appreciate a photo of those kanji on the mune! Please!

  3. Hi Dave,

    Here is your guy:


    "ICHINONJI (一文字), Shōwa (昭和, 1926-1989), Gifu – “Ichimonji” (一文字), real name Endō Masayuki (遠藤公之), born October 23rd 1890, he worked as a guntō smith."

     

    The stamp is the Showa stamp, used by the civilian Seki Cutlery Manufacturers Association between 1935 and 1942.  Most dated blades with the stamp were made in 1940-41.

  4. Charles, I hope you can get a refund unless you just want to use this as a decorative wall hanger piece.

     

    Everything is wrong about this. But I will list some things:

     

    The handle is brass, but the Japanese used copper and aluminum, never brass. The stamps on the handle are horribly wrong. The Japanese did not put flags and other marks on the copper collar call a habaki.  The Fuller groove starts too far down the blade.  And the screw and nut through the handle are the wrong style.

  5. We've all read how the order outlawing the wearing of swords, and the following efforts to Westernize Japan's military, decimated the sword making industry.  Working from memory, so forgive me if I'm off, but do I recall there were only 7 sword smiths operating when Japan decided to go back to samurai styled blades?

     

    My point being, since collectors often increase the value of items that are rare, wouldn't blades made by those smiths, before the big push to train new smiths to increase production, be worth a pretty penny and highly collectable?

     

    Just wondering.

    ; listed as a branch of Osaka arsenal.

    That might explain it.  As to the "8" coming from that branch of the Osaka arsenal .... a slight possibility, I guess, but both blades were made by Gifu, Seki smiths, and found in army fittings, so I'm thinking it might need another explanation, like a shop marking.  Verdict is still out, though.
