passthru, you are correct at first I didn't touch them up but I did get pass throughs on whatever I shot. I did later start to hone them on a diamond and conventional stone, I'll be the first to admit I'm not the best at putting an edge on things but was never able to get them as sharp as my NAP heads right out of the package. I really don't have the time to spend sharpening my NEW broadheads, I'll stick w/ my spitfires and hellrazors
