Oda Sa Tsuba

[DoTanuki yokai]

Hi, 

all I know is only the little from Markus Sesko article about the Tsuba and I’m left with some questions. 
 

https://markussesko....2/07/08/oda-samonji/

 

1. How does the other side look ? 
 

2. is the Texture original or is it also the result of the Fire, was the Tsuba even in the fire ? 
 

3. Overall dimensions 

 

Thanks

Having tried to patinate a copper tsuba in an electric oven, this is consistent with the whole tsuba being heated "at once". The edges heat up faster and thus turn brown earlier (I think a research paper on the manufacture of copper oxide stated that the temperature for the reddish-brown oxide is in the 250~300℃ range). But this could be very well be intentional, and it does not mean the tsuba was in a fire incident.

My thoughts
1. exactly the same since it's a simple sukashi

2. assuming a seppa size of 38mm the tsuba would be 75mm
3. the patina is way to uniform to be burnt, there would also be scales and the fact there's the seppa dai mark is present and clear suggest this wasn't been in the fire or been re-patinated after

So i can assume that it has a subtile nashiji texture and it is not the grown grain from the heat 

 

For my question of the other side I’m sure the Seppadai has punch marks on the other side too squeeze the Nakagoana. 

The rim looks also slightly rounded

 

So it is most likely an unimpressive piece that don’t want to distract from the Daimyos calligraphy.
Im seeing this right or do I miss something ? 
I mean the patina and execution of the cutouts are nice but overall it looks kind of plain or boring to me. 
 

What are your feelings about it ? 

Thanks so far Manuel and Nox. 
 

Maybe @vajo can check the “Reborn” (p.45)book from Sano Museum for more information ? 
(Or someone else with this book)

The texture is the result of the copper alloy, the patina just bring that out.
There's no need of punches if the nakago ana is carefully filed to accomodate a specific nakago.
Despite not being a flashy or complex piece is a well made composition and execution, patina also is very nice. Don't be fooled by the simple nature of this piece, to make a tsuba like this is not that easy as it might look.

Thanks again but I mainly thought it got the punch because of the nakagoana shape that we see on this side.

Best picture i can get from the book Christian. Its nearly to the inner side of the sheet.

 

There is no picture of the omote.

Thank you Chris, i thought it was worth a try but it looks like it is the same picture Markus Sesko got on his website.

Yes it is the same picture
