We have all probably developed our methods the work for us. And that makes it enjoyable too.
I started out with a piece of an Autum Orange shaft (from my first deer kill). Then went to buying "something better" here and there. Hooks, rollers, wood, etc. Well they all worked O.K. - but I always went back to that old piece of aluminium shafting - because it was always right there on my work bench.
So now I have sold all the various straighteners at rummage sales and my club swap meets, etc. But the old Autum Orange shaft is still in use.
If I can't get it straight with that - it becomes a stump killer.
