Hey Mike this is what I do.......
Put all three b-heads on three different arrows of course, but only shoot one b-head to practice with for the majority of your shots. Then shoot the other arrows once or twice to make sure they are on and they will still be plenty sharp to hunt with! I also got some slick trick mags and you will be highly impressed with how SHARP they are! Wow be careful puttin em together!

As far as sharpening them... you can easily buy new blades(which is probably the best thing to do) or you can try to sharpen them on a lansky style sharpener!!

But if you just shoot like I told ya you will only have one b-head that you will have to replace or sharpen blades on!!!! Good Luck!!


Ohhh and the slick trick I practice with probably took a good 50 shots into my yellow jacket target before I declared it dull!!!! You will see when you start shooting!!
