i! I am new to this forum and would like to ask for assistance in identifying 2 tsubas Any information you can provide is greatly appreciated

The first I inherted in the 1990's I was told it is XVII century and belonged to the Soten school. That is all the information I have It is 81.128 mm in diameter and 8 mm in thickness.

The 2nd I found in a pile of scrap metal at a flea market in Massachusetts about 10 years ago It is 84.25 mm in diameter and 9.45 mm in thickness. Any thoughts are greatly appreciated

Thank you! John
