So tonight I finally got around to sharpening the broadheads on my wood hunting arrows. I have been practicing with them for about 3 weeks so I have been dreading the task. Sharpening broadheads is my least favorite of all traditional archery tasks. Tried a couple of my usual tools then remembered I had a Dremel in the garage. Clamped it down in the vice on my arrow building table and in a matter of seconds I managed to trash whatever edge was left on a couple of Grizzly Bruin 2-blades. Was able to repair the damage with a file and my 2-wheel Rada in about 10 minutes, but needless to say I was disappointed. Has anyone successfully mastered sharpening broadheads with a Dremel. If so, what is your technque? In theory, it ought to be really easy.

I use this method on my Howard Hill heads. Works great.
For my Tuskers I follow the sharpening the method on their website.
I guess that’s another reason I like 2 blade heads. I use a file and touch up with a diamond hone. Hardest 2 bladed head for me to sharpen is the hill style. Because the head is so narrow and it’s hard to get at the blades to create the angle I like without filing the ferrel.
Problem with all the pull thru type ( and i own a bunch of different ones) is....they leave a jagged edge. Which may or may not be bad, and, more importantly, and i am making up numbers here...if your broadhead has bevels totalling 60 degrees ( 30 on each side) and the cutter is 50 degrees ( 25 on each side), you aren't even touching the actual edge till you remove stock from the sides. Yes, same as any sharpening system, but folks i see using them seem to give it a few whacks and proclaim something ( it is sharp or it sucks).
I like using a BOJ or Rada to sharpen the broadhead. It evens up the bevel and leaves a hollow ground blade. See the screen shot above.
I used to love Lansky but the last two sets of stones I've had have worn out and cupped or crumbled with just a few sharpenings. They replaced one but it wasn't much better. My old set, which got lost in a move was rock solid, pun intended, and I sharpened all kinds of stuff with it without issue.
I can often make any blade eve duller than when started!
Best thing I ever did for broadhead sharpening was getting a KME for straight edges and a Lansky for radius edges.
I have never tried the Dremel, but I have used a whole bunch of other sharpening methods. I, too, have trashed many a broadhead. I have two electric sharpeners, about four sets of stones/diamond surfaces, files, etc. I guess some of us just are doomed to be lousy sharpeners. My best results have come from just taking a stone and slowly working the edge until it cuts well. How I envy those who can get good results quickly.
Never used a Dremel Tool. All I use is a Rada on 2 blade heads or a mill file and a butcher's steel on my 3 blade heads.
