ODD STAMP ON SHINGUNTO

[rebcannonshooter]

I saw this on eBay today. The sword appears to be legit, and of good quality. But I've never seen these stamps before, or in this location. The nakago is mumei. 

Hey Bruce and/or Kiipu do you have anything like this on file? What do you guys think?

  Thanks Tom M.

Tom:

Just a guess, however "sword grade steel", according to google app and the document below has a very similar stamp listed as Nagoya. No idea if they are authentic.

Thanks John,

The "sword grade steel" makes sense. I've seen the letter 'k' inside a star before, but not the 'k' inside a circle inside a star inside another circle! Just wondering if any of the other militaria collectors have seen such a thing. Plus, "normally" aren't these types of stamps on the nakago? The location of this struck me as odd. 

thanks, Tom

Just a quick note, there is one other and it is in Bruce's Stamps of the Japanese Sword document.  Will post links later.

 

Edit: Below is the link to the other one.  It is coming from a 2015 eBay listing.

I got it from Trystan, @BANGBANGSAN on this post:

 

Here is the one posted by him on the thread.  Clearly not the same sword, so now we have 2!

Nice chart, John!  Where'd you get that one?  It matches what Trystan said about the stamp and the "Steel for Sword" kanji.

Tom,

Could you post a shot of the overall gunto for the files?  This is 2 of these, and I don't have a good photo of the sword itself.

Not sure, though here is another one. They are referencing Japanese bayonet markings.

Here ya go. Unfortunately no photo of whole sugata or closeups of nakago

 

Not my photos or listing - just sharing for posterity

Thanks Sam!  Interesting mix of patinated, pierced tsuba on what appears to be late war tsuka and saya.

That's the mark of 金城鑿岩機株式会社 (Kaneshiro Seizo KK), one of the subcontractors that made Type 30 bayonets. I mentioned it in another post. It's different from the encircled star 'K' mark on this sword.

Here is more information about Army sword steel 刀剣鋼（陸軍）.

Ok, I re-read the other thread.  I had originally thought you were saying that both stamps were of Kaneshiro, but you did not mean that.  You simply said they reminded you of the bayonet stamps.
