Cursive kanji Polishers signature?

[Mike0820]

Hello, I’m an amateur nohinto collector and claim to know nothing about it. Just learning. I picked up this katana in ww2 gunto Shirasaya. The nakago is signed omi no Kami fujiwara norihiro, can’t find much on the sword maker but I found something interesting on the burnishing under the fuchi. Looks like very small cursive kanji characters that possibly the polisher wrote. Can anyone tell me more about this or possibly translate the cursive kanji for me? Thank you in advance.

Yes I think it's a togishi's inscription

 

研上 sharpened

還 (not sure about this one) 之謹 - maybe means something like 'returned with care'?

 

Other side is a date Showa 17, August

That’s awesome! Thank you. Is this something commonly seen?

I think that the 2^nd line means the polisher’s name.

研上 – Polished

譲之謹 – Noriyuki/Masayuki (or other readings) respectfully

I apologize for the incorrect terms and spelling. I am very new to this. All help and opinions and thoughts are welcomed and I am grateful for any and all help, knowledge. I will be posting more pictures of the sword and also of a wakazashi I picked up locally at a flea market. As this is a translation post I will not add on it in this post, but will instead post in a more general part of the forum. Much respect and thanks. You guys are great.
