Thank you for the information. I will look into it some more. In regards to cleaning the blade, I started with methylated spirits and then with some more research was told that WD40 was good to remove the black coating. I used it yesterday and it worked extremely well with no problems to the blade currently. I’ll post a photo today of the cleaned blade. There is some light surface rusting that could be polished out I feel. I’ve heard that sewing machine oil is sufficient for blade maintenance after this? I’m just thinking of the ease of maintenance for the older person I’m getting this information for.
in regards to the swordsmith’s name, if below is correct, I’d assume it would be with an ‘S’ not ‘z’?
