Good on you!
I've really enjoyed my scythe outfit from Scythe Supply.
Let me tell you this: The scythe is a perfect example of the old adage that says: "Let the tool do the work."
It really is worth it to learn to scythe correctly. When you do it right, you'll feel worked but not overly tired*. If you do it wrong, you'll feel overwork, sore, and bushed.
Think "zen", if you will. There is a certain "place" where you are scything correctly and it almost seems to good to be true, because it isn't difficult. It just flows.
But it is true. Proper use of the scythe means a lot less work than most people think. My wife was watching me scythe and said it to me: "Wow, John you're really working hard!". But, I wasn't. I noticed the same thing when watching Youtube videos. They really look like they are working harder than they are. What the person above said about 'leverage' is true. With a scythe, leverage either works for you or against you. Either way, leverage is very powerful.
As for peening, watch some Youtube videos, and relax. Lots of easy, small hits is the trick. No need to bang away.
* = couch potatoes will feel overworked, but that's our dang fault!
