The Rada sharpener works pretty good.
I'm gonna check out the Smith pocket pal.

I been trying to sharpen some old bear razor heads, cant get the edge I want no matter how or what I use but I got a buddy that cab use a file and have them shaving sharp in under a minute

Been out "shooting" the recurve. Heat, Humidity, Ants and Ball Gnats.
Already managed to lose a brand new arrow.
Aint no way I'm gonna be ready to hunt with this thing in Oct.
Done drug out the Bowtech.

Get a three sided jewelstik and a Razor Edge Systems Arrowhead guide.

Then watch https://www.youtube.com/watch?v=MtNBQoVlz80 He sharpens Simmon heads, but the same process will get bear and any other two blade broadhead screaming sharp! I sharpen broadheads, knives and everything using the same technique, when I say something is sharp, don't test it with skin!! Not bragging, it's just that simple process works that well.
