Geronimo,
Spent some time this morning sharpening my G5 so you could indeed shave paper with it. I had to sharpen each blade individually, not like they show on their web sight.
Although I would recommend following their instructions because I' d rather cut venison than paper!. The angle of the broadhead is such that it will be plenty sharp when shot through a deer. If you don' t have a diamond stone, your wasting your time trying to sharpen anything...In My Humble Opinion! You could purchase their sharpener and use it on all your knives too! Hope this helps. Actually, if it shoots to the point of aim, its far better than the replaceable razorblade type. But each to his own. I' ll give you $15 for your G5' s if you want to get rid of them.

Hope this helps.
