Maybe this should go as a product review, but heck, I'm a bow buildernot a computer guy.
I got myself one of these KME Broadhead Sharpeners and I'm here to tell you, if you use a two blade broadhead...This thing is a must!
I took the dullest most bent up (from the MFR) that I had and put it into the KME Broadhead Sharpener and started with 220 grit wet paper and in about 50 strokes the edge was profiled. I then changed paper to 400 grit, 600 grit, then jumped to 1500 grit and finished with 2000 grit. And now she's scary sharp!
