Quick video on file sharpening a broadhead.
Just a quick video on how I sharpen a broadhead. In this case it's a Zwickey Eskimo. From a new, factory edge to shaving sharp in a couple of minutes per head. Notice I start filing the flatter bevel out at the tip, reducing the metal thickness, then slow down and work the entire edge, blending it all together...finishing with a round file to give the small little serrations that Hill would do by dragging a file corner down the edge. I do all subsequent touchups with the round file once the new head has the edge set. I use a bit of force at the beginning, and that, coupled with the fast filing will build up enough heat in the metal to soften the hot melt glue on the shaft taper so I have to be careful. You can hear the tone change of the filing pressure as it lightens and I finish with light strokes back to front in the off-side so my serrations face forward. This gives the edge the look that is seen in my previous post on That Fil...
