Help with signature on Wakizashi. Looks like MASAUJI?

Got a bit of a backlog here, so finally getting around to this one. I tried to get a better picture or use corn starch, but with the current humidity in the office it does not want to stick.

 

As best I can tell it is 政 氏 作 - MASA UJI SAKU

 

Yasurime on the tang are mostly gone, as is most of the tagane-makura, but I can still see some tagane.

I agree: Masauji Saku.
