Sharpening and peening a scythe

Something to note, the scythe blade has a 90 degree edge that goes up in the back of it. This is not for styling, the idea is that if you press your sharpening rock against it and also against the edge of the blade, you will keep a regular and ideal angle for your blade.

This guy uses a smaller stone and does not lean on the back pretrusion as they used to do, I mean, it was added for that reason.
