IronDragon, Thanks for the ozark hoe, I've never seen that design before. I have a little garden on the edge of a stream with really rocky soil, I can see that design working there.
Frosty, thanks for the detailed directions, I will try that. The commercial handles available are pretty poor and too expensive for most locals. In general people cut their own tool handles in the forest.
An ard is simply a scratch plow as JHCC said. The ones people use here are made from two pieces of oak with a steel point. I have seen old stone points, but nobody uses those any more. I'll try to come up with a photo. People pull the plows with a horse, usually a mustang, or a donkey. In the past they used oxen with a head yoke, but that has pretty much died out.
