This belongs to a half Japanese freind who inherited it from his grandfather. He's wanting to know more about it as it came to his possession with no backstory or documentation. Any guesses or rough estimations are welcome.

I can try but it's way out of polish. Like I mentioned it's hard to see any activity even in person. Like I noted on the paper, it looks like a komaru boshi, itame hada and it's got pretty decent fumbari.

Forgot to add it has a shallow iori mune

Lf opinions on this. It's hard to see any activity in the hamon or hada, what I can see is listed in the photo of my notes. I'm thinking osuriage koto probably late kamakura early nambokucho, but I'm not an expert. Any other opinions, school or smith?

Don't use gun oil on swords. A lot of them have cleaning elements meant to dissolve powder residue, lead, copper fouling etc in them, as well as lubricants that may or may not come off with isopropyl. This applies to things like wd40 and 3 in 1, break free, etc as well. Stick with sword oil or mineral oil.

Got any close ups of hamon activity?

Beat me to the reply. Etsy is a scammers paradise.

Looks like masayoshi to me

Rats are commonly depicted as they are one of the 12 animals of the Chinese zodiac. You see these quite often in tosogu, take a look at the wild things thread for examples.

Thanks for the advice. I go every two years.
