Nothing wrong with a Bitzenberger but I prefer the Arizona EZ Fletch. Arrow saw......if you cut arrows properly you don't need an arrow squaring device. If your going to have a pro shop cut your arrows you might as well ask them to square them also. Arrow spinner (for broadheads).....you can devise one from what you have in your kitchen cupboard.......
2 mugs will do just as good.
Epoxy.........for your inserts........don't get the quick cure stuff. Quick cures are brittle and the insert/arrow bonding will break.
Glues. Gorilla super glue, Loctite Ultra Gel Control, Bohning Platinum Fletch Tite...
