Edo period katana sword Signature

I can’t authenticate it but it reads “Bishu Osa...”. Unfortunately the rest of the signature was cut off when the blade was shortened.

 

So this is a sword made at a place called Osafune in Bizen province. It’s a place well known for sword manufacture pre-1600 (and again a couple of centuries later) but it’s likely that this blade is one of the mass-produced blades made for the wars of this time. So probably earlier than Edo period.

Do you think it was period cut to meet regulations etc.? Also thanks for the response!

Dear Joe.

 

There are several reasons for shortening a sword and no way of telling which one applies to this sword.  What is it's length now?

 

All the best.

The overall length is 96.5 cm or 38 inches. The blade length is 25.2 inches- about 64 cm. The width is about 3.1 cm or 1.2 inches.

Dear Joe.

 

Compare with this one, https://www.aoijapan.com/katana-bishu-osafune-sukesada/  and it would seem possible that the lower mekugi ana on your sword is the original, hence you can get a good idea about the original length.  You might also find this article interesting,  https://markussesko.com/2018/04/25/tensho-suriage-and-keicho-suriage/  

 

Can we see a shot of the whole blade please?

 

All the best.
