Wakizashi Mei, please help.

[Itomagoi]

Hello, I would be grateful if someone could translate this signature for me.

There is definitely mention of Kaneharu but that is it

[Shugyosha]

大和守口口作 - Yamato kami blank blank saku. 

 

Looking down the list of smiths with the title "Yamato Kami" in Sesko's Compendium to try to fill in the blanks, a plausible option might be Ujinaga (氏命) based on the shapes I imagine I'm seeing but it's a bit of a guess. Do you have a better photo Peter or can you do anything to highlight the strokes in these kanji to make them a little clearer?

[Itomagoi]

I try it, John.
