Sorry Guys,
We were working at the shop today so I'm late repsonding.
I just talked to Greg on the phone. So that's one answered.
Owlbait, I didn't see any mention of Simmons broadheads on the thread... :D
The answer to that is yes, and no. The best way to sharpen an inside curve is with a round rod, slip stone, or steel.
A big flat stone just can't line up with the concave blade shape. If you turn the sharpener upside-down so that the roller is up, you can rest the steel on the roller and blade and sharpen any inside curve. You just need to work the system backwards: Move the steel not the sharpener.
This same technique works with straight blades too and is a great time saver on tuff to sharpen broadheads like the grizzlys. You can use a file to quickly work the factory bevel down, then go to the stones as usual.

Yes you can sharpen broadheads that are mounted but, it's a good idea to presharpen them first because 30 inches of shaft moving back and forth with the sharpener will require a pretty big work area! For touch ups on the shaft, I would suggest the upside down method. You could even do it on a stump in the field. Give me a call. I don't get to do in person demos very often and always enjoy meeting a fellow Tradganger!
