Help with ID of this Honesuki please?

I am hopeful that some of the wise members of KKF can help me with the manufacturer of this honesuki. I got it on eBay as part of a small lot of used knives. The lot included a Misono 440 180mm gyuto and a Masamoto yanagi, which needs a lot of TLC (hell, I have plenty of time to work on it now)

Wow. Apart from the 研 the rest is a mystery.

It's 研波流 Togiharu, which is a house brand of Korin in NYC.

That's 波流? (笑) Well done!

Ojisan, thank you very much for taking the time for solving this mystery for me! and thank you also Ken for the assist.
