Got a quick question for you guys. First let me give you all a little background so you can better answer my question.

I shot a doe back in October. Clean pass through, double lung shot, couldnt have asked for anything better. Retrieved the arrow and broadhead, both ingood condition. Well we sharpened the broadhead a bit cause it did stick in the ground. I got a new crossbow for Christmas, and am trying to take another doe, so i figured i would just use the same one i took my other one wiht. So i have been sighting my new bow in with that broadhead and arrow and have shot it into a foam target around 10 or so times? It still flies true so there is nothing wrong with it. I need to resharpen it i think. So my question is how much would it take to return it to "razor sharp" I'll be using a G5 broadhead sharpener. Also how could i test its shaprness??

Thanks in advance.
