I have sharpened several broadheads on it since i got it, and what can i say...its great! Very fool proof and i love that, just gotta keep files clean! Ive sharpened 6 Ace Express 165gr to a real sharp/ridgid edge that shaves hair and blows up rubberbands! I have it down to a systen for my Ace's, sharpie edges, 20 "Hard" passes per side, then when a good burr is raised, i actually draw the head the opposite way 10 passes! Its a wicked edge! My only real ? here is... I have some Tusker Aztec 175gr heads i wanna sharpen, and possible use for elk this fall! They just have a slight factory grind on them now, with enough work on the tru angle, will i be able to establish a good edge on these, as well as remove enough metal to get them down into the 160gr(+5-7gr)realm i need for spine?
