Hello C4RL,
Wow, thank you very much for posting this interesting link which I think isn't against any rules.
And as well for sharing parts of your collection which you have partly very nicely restored, congrats!
And sorry but I never have seen such a tool in your last images before.
My one I bought some time ago on a German online platform, it appeals to my eyes and I remembered my childhood when grandma used a similar tool in the garden. It was very rusty, I cleaned it with steel wool and oiled the handle, the wood was very dry. I plan to sharpen the edge again.
Regards,
Detlef
