I have all sorts of things in my pile of metal. My daughter captured this piece years ago and recently returned it , It was a “bill hook” “A billhook is a versatile cutting tool used widely in agriculture and forestry for cutting woody material such as shrubs, small trees and branches. It is distinct from the sickle.”It is very old.. well older than me and I cut off where it joined to the handle.It seemed to want to have a new life so I set it loose upon the seas…. Well sort of.
