Here is how I (and many others!) get Woodsman and Snuffer heads sharp-
1. Take a black marker and color in the blade edges until no shiny metal is showing
2. Take a file that is wider than the head and lay it on a flat surface. I nailed a pc. of 1"x 1" on my bench to keep the file from sliding. Lay two edges (V down) on the file pushing the head away from you (lenghtways on the file). Take x number strokes (I use 20 to start) and rotate the head. Repeat until all 3 sides have been done.
3. You need to repeat this process until you have an even, shiny surface on the cutting edges of the head. ALWAYS use the same amount of strokes on each side of the broadhead. Keep track, I usually stick with 20 strokes per side until I achieve the even, shiny surface. I start with a fairly firm pressure and decrease it as I progress.
4. After the edges are "roughed in, I repeat the process with a decreaing number of strokes- 20x3, 16x3, 14x3.....after the first head, you will get a feel for it and develop a system that works for you.
5. I finish up at 1 stroke per side
6. I then finish with a diamond file or diamond stone. At this time, I hold the broadhead by a single blade (use a leather glove) with the V up. I lay the file on the two blades and file from the back of the head to the front, using the same number of strokes per side in the same type of descending pattern. I actually start with a medium diamond file and then repeat the process with a fine diamond file.
7. SCARY SHARP! Will shave hair with no problem! After you've went thru this procedure, a quick touch up with a diamond file is all that is needed to get the broadhead ready to go again. I hope I wrote this so that it is understandable. I fought for years to get Snuffers sharp and this is what works for me. Good Luck! Mike
