Hello all, new to the forum and have no knowledge of appraisal aside from research done the past couple of weeks. But here are my guesses: #1 Considering the long nagasa, koshi zori sugata, and ko-choji? hamon, would have originally guessed it is a Bizen school sword from the Nanbokucho era. It's hard for me to see, but I think it has ayasugi-hada, so I am now guessing it is a shinto sword made by Gassan Sadakazu during the Edo period. #2 After looking at so many Shoshu style swords, it feels like the closest with that larger kissaki that has kind of a wide taper, and it has a suguha hamon with kin-tsuji and saka-ashi. It looks very similar to Fujiwara Masahiro's work so my guess is it's his work from the keicho shinto era. #3 It has a slim shinogi ji, notare midare hamon, and also appears similar to Yamato Uda school style. It has a deep sori and 3 mekugi ana. I guess it is an Uda Kunifusa.
