Yes, it's a hand forged colonial period hoe! Nice find. I have dug two - ever! I cleaned it with a bristle brush and tack hammer with 1/4" chisel for the big rust, then outside put it in a baking pan with a lot of melted microcrystalline wax and heated the whole thing up until the iron started to bubble and continued until the bubbles were gone. The air and moisture are driven out and the wax fills the pores to preserve it.
At first I was maybe looking for some nylon stockings, but yes I do think that it is a hand forged hoe but another mystery is the size of the hole for the handle is large which doesn't fit the hoe thing. We use to have a heavier version of a hoe which we called a "pick ax" which did have a heavier handle. Anyway a great find.
Had a hull of a steel boat done, tarped, and the company wanted to prime 30 minutes after a section was done. Rust starts to re-appear.Thank you smokeythecat for your ID and for the specific method of preserving. I have put it through electrolysis to expose more if it but it is already rerusting as I hadn’t applied anything for preservation yet. Hmmm I will have to try the wax method! I am happy to hear of the age...so...maybe mid to late 1700s? Yes..the wings seem a bit fragile.
Thanks again!
