I agree with John's thoughts. It looks to be early Shinto period. I think I can see some hamon in the pics, and blade appears healthy enough to take a polish. Need to see it without habaki to help with that call. Just like #2, in its current condition, it is not worth much being an unsigned, out of polish blade with no koshirae or shira-saya.

Looks to be from the late koto period, judging by the color and shape of the nakago. The way the blade width tapers down quickly after the hamachi makes it appear theat it has been to the polisher many times. If this is the case, the hamon will be very close to the edge, or possibly run off the edge, killing the artistic and functional value. In the current state of polish, we cannot see the hamon to judge if it can be polished again. In it's current state of polish, with no habaki, no koshirae, it is not worth much. If it can be bought cheaply, it may be worth restoring.

That is a decent kozuka handle and kogatana blade.

Although I'm not a believer in the fortune telling (with cards and palms), I do find it facinating that it was done upon swords. Please post more info if you get it.

Sending it to shinsa is the best way to know for sure, but I think it is worth a shot.

@BazzaLove the kozuka and the kogatana!

Can't say I have ever seen that. Pics!

So now we have @paulatim with a mumei RS, @BANGBANGSAN that had an mumei RS. Now we can add mine to the short list. Plus, mine has the celluloid same' as well. This one is getting very strange.

Yes it is. See my post about it here...

Smith is Fujiyasu Masahira. Still alive and still working. https://youtu.be/rPQn9DsDcWg

The old gentleman I bought these from is holding on to his father's kai-gunto. It is signed 特殊鋼以井戸秀俊作 which is Tokushu-kō motte Ido Hidetoshi saku. The first part, Tokushu-kō Motte is "Special Steel Mix". Best I have researched, and what I see in person is that it is a mix of stainless and carbon steel. He has owned all these swords for 35 years, when his father gave them to him. His father got the kai-gunto while fighting in Guadal-Canal. The others he got while stationed in Tokyo from 1945-1946.

So if this is unusual, that makes 3 out of 4 that are unusual. The fourth being the "last ditch" NCO.

Don't think I'll be keeping the NCO. Doesn't really fit the rest of my collection.

May be odd, maybe not. I have seen family wakizashi in Army and Navy mounts, but never seen a stainless anchor stamped version. Nagasa is 22" (55.8 cm). All numbers on small seppa, large ray seppa, tsuba, fuchi, and habaki match.

Battle damage?

I could only wish.

Kozuka blade by Masahira to commemorate the 60th anniversary of NBTHK in Fukushima.

So 2 of the four swords I just got are on the odd side. Wonder how the next two will fare. Lol

The look reminds me of the surface as it has been hammered, before the files and shavers make everything on a level plane. It is almost as if it was a rush job ...no one cares about the nakago... it's covered by the tsuka...get it out there where it belongs...hurry hurry!

Due to the condition of the polish, it is difficult to tell. I believe some never-dull has been over the surface. I have the worthless bright white led lights in every room of the house. I would like to check it in a good old dim florescent light or early or late sunlight.

Also just realized this has the celluloid same. So the RS and my Emura both have celluloid same. I've learned something tonight.
