Help needed translating dual mei shinshinto blade…

[aeguy]

Last Thursday I purchased what I believe to be a shinshinto katana in full koshirae. It has a dual mei where the tachi mei side reads, “Bizen (no) Suke Fujiwara Munetsugu” (if desired, I will upload an image of this mei in a separate, part 2 post as the file size is too large to include in this post) & the katana mei side that I need help translating is depicted here…
I think it reads in part, “Yasu-???-Yoshi-Tsune-Toshi”, but this is also likely completely wrong. Hence, my request for NMB translation assistance. Thank You in advance for any & all assistance provided.

My guess would be

安佐美常利　

Asami (or Anzami) Tsunetoshi 

or possibly Asa Mitsutoshi

 

but those are just wild guesses. 安佐 (Asa) is a rare last name in Japan, as is 阿佐美 (Asami).

But the combination of 安+佐美 doesn't appear anywhere. Asa Mitsutoshi feels like a bit of a stretch as well. 

 

Anyway, in the absence of any other clues, I would say it is the name of the owner.

Thank You Steve M! I know this is likely a simple translation… IF that is, you are also fluent in Nihongo & also recognize the inference(s) being made here. It’s those last parts that have me stumped on this one. Regardless, the effort you’ve made on my behalf is Greatly Appreciated! Domo Arrigatogozaimasu!! 🙏
