Sharpen Sickle by Peening?
I've read, and seen youtube about sharpening a sickle or scythe by cold hammering the edge to a very thin, sharp edge. Although I get the idea of coldsmithing (kinda) it just seems to be something that I don't have the knack for yet. I also don't have some of the specialized jigs I've seen on youtube.
Do any of you have experience with sharpening an edge by hammering it while cold? Tips?
