Attention Mantetsu Owners: A Survey

[Bruce Pennington]

I would call it very dark brown. But again, I don’t have it in hand either. There are black ones, and while they are not as common, there does not seem to be any significance to them, unless everything else has been painted black. We have many example of those. But even those, we do not know the significance.

Dunno if Bruce got this one.

Interesting.  Yes, It's on file, but from a year ago, April 2025.  Maybe he didn't get his reserve the first time.  Thanks Marcin!

Hello Jerald, 

 

Does your sword have koshirae or is it just the blade? Can you post a photo of the full length of the nakago? 

[Bruce Pennington]

Thanks, @Giantmalamute2003 Jerald!  I assume you already know, but just in case - Spring 1939, Kao Isshin Mantetsu made; serial RO 429.

 

I'd love some shots of the blade and fittings, as well, if you don't mind.

I wonder what could have chewed up the Nakago like that. 

I can not imagine why something like that would be done intentionally.

Wartime damage perhaps? Would love to see more of the sword.

Thus the chart now has "RA" in '41, but with a footnote: (note: Pasting the chart on the NMB site causes spacing distortion)

Yes,

Autumn 1942, Ku 347 Koa Isshin stamped "143."

Thanks!

Found the above Spring 1939 posted by GiantMalamute on EBay here: Spring 1939 Mantetsu

 

Note the shape of the nakago jiri and the hamon. Although, I can’t tell if the hamon’s appearance is the result of some post-war fiddling.

Good eye there, Con!  There might have been a little more experimentation in the first couple of years.  Photos for later when the link goes dead:

Jerald posted those pics here on April 16th - slighly larger versions, that is.
