Matt, just to clear something up, the picture I posted above was a left beveled home made broadhead.
Below is a picture of a Grizzly before and after sharpening:
Got it, I still understood what you mean.......that you want the lead edge of the bevel spinning into the target not the bevel itself. Good stuff.
Grizzly make a screw in version or do I have to mount them on an adapter?? I haven't graduated to wood arrows yet.
