And these are a pair of male and female dragons on each side a katana I have.

Here's a partially exposed dragon horimono in relief on an osuriage katakuriha wakizashi I have.

John, you make an excellent point on the local climate. I wouldn't do what I do if I lived in the tropics, or lived close to the ocean. And I keep my house air conditioned 24/7, and don't have my windows often very often.

Now I thoroughly curious...are there any members out there who can share their experience with leaving their swords in koshirae, oiled or unoiled, only to find them rusted upon the next inspection of the sword? If rust was found, how long was the interval between inspections for the rust to develop, and how severe was the rust? It's good to have factual data points on this matter for the thread originator, rather than just hearsay or theories.

I guess I must be lucky then...but just to point out that nihonto are instruments of warfare, and weren't originally designed to be babied.

It's fun to see the weekly parade of Kiyomaros and Kotetsus listed for auction.

Yes, I was suspecting that it was a suriage nagamaki too, but gosh, at over 4 lbs in weight just for the blade, that would have been quite a polearm to swing around. So maybe the votive word story in the listing holds some water.

Here's another interesting one on Yahoo Auctions. A 3+ foot long shobuzukuri odachi in koshirae. The supposed story of how the sword is from a museum in LA seems imaginative. The hitatsura hamon looks quite unique to me, but the shape and quality of the habaki doesn't give me a good feeling. I always think that good blades always come with a high quality habaki. https://www.jauce.com/auction/r1159567193

I have been collecting nihonto for over 20 years, and I've always been one to transfer them from their shirosaya to the koshirae once I receive them, and I never keep them oiled either, with no ill effect. Some of my swords have been in their koshirae for over 20 years on my sword rack, unoiled, without developing any rust. And until this year, I lived in a city where the humidity in my house was about 50%. I prefer to keep my swords in their koshirae because I like the feel of how a sword was intended to be handled, in koshirae. And also, I have an unfounded phobia of my hand slipping on the shirosaya handle, and my hand getting cut, so a tsuba is always nice to have. So now I have a huge stack of shirosaya over the years that I really need to get sorted and tagged, ha ha. Maybe it's also because most of my swords are TH and below, and not Juyo or TJ, so I'm not as concerned with keeping them in absolutely pristine condition.

I have a similar issue with a sword I'm getting exported to the US. The torokusho information didn't match what was in the system because it was from the 1950s, so I have to wait for the local govt board to convene in Nov, correct the problem, and then wait another 3 weeks for the de-registration to export.

I have some good news to share today! I received a call from the supervisor at my local USPS office to say that they "found" my sword after 4 days of it going missing, and I've just picked it up and have verified that it's undamaged. I assume that the USPS theft report an the police report that I filed helped get the necessary attention, and the USPS supervisor will also be looking into the matter of the fake delivery attempt by his delivery person. Thanks again to everyone for their helpful suggestions on addressing the situation!

I agree with you, and the majority of the Eirakudo items don't reach their reserve, and they cancel the bids at the end. I really don't know why they even bother listing their stuff on Yahoo Auctions.

I'm not sure if it's just my middle aged eyesight...but the space where the bottom character used to reside kind of looks like a "mitsu" (光) to me, ,with the long curl of the lower right stroke standing out against the standard rust pattern.

I wonder how much this will eventually go for; what looks to be an ubu Sadatoshi tachi with a 87.3cm nagasa. https://www.jauce.com/auction/1157055481

Thanks for the suggestion to post this on Reddit/Katanas, and also on the USPS auction site. I'll keep a lookout for my sword on it.
