I purchased a new scythe from Botan this summer and am really impressed with this very useful tool. I've been establishing an edible forest garden in an old field and use the scythe to cut the grass around individual trees.
What I'm concerned about is my new level of scythe anxiety. Botan took me out and had me cutting. That was great. HE also showed me how to peen. I've looked at videos of peening, but I"m really worried about actually doing it. I don't want to destroy or even damage a really powerful tool.
I'm going to pick up Ian's book with hopes that a good resource will make peening possible.
Just start with light, careful blows and increase the force as you gain confidence. It's really not that hard (just tedious) and even if you end up damaging your edge with a misplaced blow or peening too much, it's just part of the learning experience and it's repairable 99.99% of the time. Scythe blades may last a very long time when taken care of properly, but they're ultimately consumable. So jump right into the process and start getting your feet wet!
