I was looking for the Korean hand plow on Amazon, but there are so many, and I’d like one that is about the size you showed, roughly 10-11” it looks like. Too many to choose from and I can’t tell what’s good. Wondering where else I might look for such a thing. It looks sharp as all get out.
I’d ask locally at your Hardware Store or even Home Depot or Lowes.
Kinsman sells the one I own if you want the exact same:
