https://www.ebay.com.au/itm/205749037590 Something similar? The one you are looking at is cheaper and better in my opinion - no idea what the theme is but another in Sasano's book 212. page 272 says Shimizu and described as "Butterflies"? [It is not particularly close in design though]

One thing missing from most Soten tsuba battle scenes - the lack of blood splatter!

Hi Will, welcome to the forum. Could you give us some dimensions of your guard? This design seems to be difficult to find, so not common, but I found something with a rim design with more folded or carved "lobes" in Greville Cooke's "Birmingham Museum & Art Gallery Tsuba Collection V2" Not the same school I believe, as yours looks much thicker. I have a feeling I have seen another somewhere but I have a lot of books to search!

Hi Will, I found this one in the Metropolitan Museum of Art. More elaborate but has some of the features to yours. https://www.metmuseum.org/art/collection/search/29973 The hitsu shapes on yours are interesting, I think they may represent gourds like on this one.

Damon I have seen a few "collaborative" decorated tsuba - But not signed in this way. The ones I have seen have had inlay work with a signed plaque beside each piece of inlay. Would you believe there is a collaboration of SEVEN artist on one tsuba? Walters Art Museum 51.410 https://art.thewalters.org/object/51.410/ There was another collaborative tsuba here: https://www.sothebys.com/en/auctions/ecatalogue/2005/Japanese-and-korean-works-of-art-l05860/lot.852.html

Welcome to NMB Zack! A relatively common Kinai school tsuba. Some are cast but as yours has tagane-ato [punch marks aroumd the tang hole] I would think it is carved. If you look on-line and find another with the same punch marks in the identical spots - then you can worry. These dragons appear as Kawari-gata [irregular outline] or within a maru [round ] rim.

Grev, Lotus root cross section?

6A & 7A Signature: 国廣 (Kunihiro) as I thought might be the case - generally good quality iron. There are many like 1A - I have a theory they were "Shiiremono" (仕入れ物) - ready made for quick sale. None of these were very well done or elaborately inlaid. They tend to be the same shape as well.

Steve that one is from an auction of ten back in 2013 - https://www.bonhams.com/auction/21106/lot/202/ten-various-iron-tsuba-17th-to-18th-century/ information is very limited "another of lozenge form carved with mokume" - doesn't say much for such a nice piece

Yotsu Fuji ? What to make of this one - not Itomaki-gata but I don't think it represents Fuji-san either [the sides are flat not curved]? And this?

You could well be right Jean. Not a lot of difference, just three little sticks [maybe the maker was a bit lazy and didn't want to do the extra cuts ] The umbrella handle is what we need to look for apparently - unless it is lost in the seppa-dai? Mecox's example has avoided the cut out "sticks" altogether [clever] Image taken from a post by Mal [Mecox] https://www.militaria.co.za/nmb/topic/39845-tsuba-reading/ Cut through the middleman and get a tsuba umbrella! - I would not recommend a sukashi design myself
