I have found a couple of tools that really help to sharpen the Grizzly's.
1. First I need a good articulating vise to hold those rascals. Harbor Freight has an excellent hobby vise that uses a suction cup to stick to my kitchen table. The vise will turn up, down and sideways in more ways than a Yoga master.
2. Next is a nice Color TV, cause many enjoyable evenings are spent sharpening Grizzly's in front of the Discovery Channel.
3. File. Use a nice new file with some type of file handle. Your hands will get pretty sore without the handle. My favorite file is of a triangular shape. The Triangle shape is a stiffer file than a standard 6 or 8 inch flat file. Chalk up the file and only push the file, never drag backward. Smooth easy strokes, removing metal slowly. Lay that file down at a low angle and don't be afraid of taking off metal. Until you get the hang of it expect to shave some off the ferrule. Use a Sharpie marker as Dykem (metal stain) if you're unsure of what you're doing to the edge. Push the file into the edge you're sharpening.
4. Medium India Oil stone and a bit of mineral oil. The opposite side of the bevel edge should have a faint bevel line from the Oil stone. Be gentle on this side, pushing the stone into the edge of the broadhead.
5. One hairy left forearm. About his time of year my left forearm is always shaved off of most of the hair. I know of no better way to test my Grizzly's than the shave the hair off my left forearm (I'm right handed) For you lefties, well you guys have shaved right forearms I guess.
Sharpen the bevel side with the file, turn the broadhead over, place in opposite side of the vise and sharpen the non-bevel side with the Oil stone. The oil stone will actually bring you to the razor edge. Again, I'll keep the braodhead stationary nad move the stone voer the edge, like you're trying to shave off a peice of the stone. Keep some oil on the stone and it won't clog up with metal filings. If you've got an Arkansas Hard Stone use that the take off the burr if you don't like a burr edge.
Grizzly's are quite easy to sharpen, for me the trick is to mount that rascal into a vise that I can adjust for comfortable filing & stoning
I don't like using aluminum broadhead adapters on the Grizzly broadhead, since the aluminum adapter becomes a weak point. Steel Broadhead adapters come in 75, 100 and 125 grain options. JB Weld epoxy works best for me as adhesive. Tough stuff, never had a failure.
I've noticed that shooting properly sharpened Grizzly's into 2 by 4 construction lumber results in the wood splitting due to the rotational force of the bevel. Backs up what Doc Ashby said about the broadhead spinning through animals.
