It's an antique garden implement that came from my husband's uncle's farm here in upstate NY.
And it's my absolute favorite hoe, because it chops so well. I've never seen anything like it. The blade is curved, with a thin edge (better for cutting), and it is angled with respect to the handle.
And the handle is nearly gone. Pity. I use it anyway...
Anybody have any ideas about this hoe?
