I use a semi-sharp broadhead. I lay it flat on the shaft and push into the vane or feather. I then run it back and forth until all the gule is off, as well as the fletching. The broadhead should be sharp, but not shave hair to work best. I forgot to mention I use a 3 blade head, two or four blade heads won't work to well.
