In the Andes we have a couple tools for field work that seem a bit unique to the region. Least unique among these would be the grass hook or hand scythe. Not as common nowadays in the States, but still around. I just watched the first episode of The Beverly Hillbillies with my kids, and noticed somebody holding a hand scythe somewhere in there.
Then there are two similar hoe/pick/shovel specimens that I cannot find very well online at all. One of these two tools isn't sure if it's more like a hoe or a pick. It's used for harvesting potatoes. The blade is maybe 8- 12 inches long and 3 inches or less wide. A sort of golf stroke, sends the blade deep into the soil under the root ball. One good upward tug on the handle, and the whole ball comes up, you flip it to the side and scatter it (conveniently downhill in the mountains). I haven't used other potato harvesting tools such as forks to compare results. (Conclusion: it really is equivalent to a smaller pick, but only has the blade end, no pick. I imagine that makes it a somewhat safer tool than a typical pick when working in tight clusters of three or four people.
The other of those two specimens isn't sure if it's a hoe or an edging spade. It's great for mounding rows. They call it a
lampa. It's probably the most similar in function to a field hoe, but looks like an edging spade that got bent way over. This seems to be a decent example:

Lastly there's a tool called the Chaquitaclla ("Chahkee tak-leah") and I did find a little video showing it off.

I could be missing something obvious because I don't have a farming background in the States, and I'm a foreigner in SA-- but I think these tools are generally distinct to Andean field work. But if I moved back north, I'd want to imitate them.
