RE: Feather burner/Choppers
You can leave a burn mark on the shaft with the burner if you aren't careful. I don't know of a way you can get a consistent burn without the feather being on the shaft first. And they stink!
I prefer a chopper myself--the Vario is great. Probably going to start using 4-4" feathers since feathers have shrunk--can't get two good 5" cuts anymore.
