The inexspensive ones that I found appeared to be cheaply made so I passed on them.
I found one that was of good quality but was way over priced in my opinion.
I found this at Canadian Tire and it worked like a charm to remove old fletching and scrape off old glue also.
All the spare blades store in the handle of the knife.
When all the bade sections are used you just slide the thumb thingy back all the way and it loads a new blade.
Push it forward and you're ready to go again.
The knife was $15 and a pack of spare blades was $10.
So for $25 plus tax I should be able to remove all my old fletching for the rest of my life!
