Kanesada ?

[Ian B3HR2UH]

I was sent the attached pretty rough photo for  translation but I am struggling with it. I read the last three characters as Kanesada saku but have done no good with the earlier ones . It seems to be a Showa piece . Does anyone recognise the smith 

Thanks

□□関岡田兼定作之 - ?? Seki Okada Kanesada made this.

The first two characters may be 濃州 – Noshu.

Looks like "Okada" 岡田 兼定, he's listed as a Seki Kaji Tosho and made both Gendai and Showato. Rated Chuge Saku by Akihide.
