Gents, Thank you for your help on this.

I recently acquired this from the estate of a WW2 veteran. I scoured the lists of kanji and the closest I could come on a translation was Kaneuji Saku. I might be way off, but I did try. There are also three kanji that are etched into the blade. They were cut in deep v groove. The blade does have temper lines. They are hard to see, but each looks like a mountain with twin peaks. See the photo of this below in which I pointed to them with red arrows. If I need to post more photos or measurements please let me know? Any help will be appreciated on this. Thanks
