The exact directions are on the Three Rivers site in the form of a down load of the Hill pamphlet. What is pretty much the same, except i use a Grobet 8" and a Grizzly file. On double bevels I take the edge down with the Grobet and in the process rob quite a lot from the ferrule. i finsh with extemely light strokes. Then I hit it with a diamond hone, then if I ambitious a leather strap with a buffing compound. Virtually shaving sharp. Then I take the Grizzly file and use the corner, the Grizzly file has rounded narrow sides which causes the teeth to be very sharp and very abrupt, and take two strokes on one side, while holding the broadhead pointing towards me in an arrow holder that supports the arrow and the head, from back to about half way and then the second stroke from half way to the tip. Repete for the other blade. If I am using left wing feathers I hold the broadhead in my left hand, so the teeth are biting in the direction of the arrows rotation, If I am using right wing feathers I hold the arrow in the right hand and the file in the left,(it helps to be ambidextrous). I have heard of guys doing all four sides, for me there is a difference between rough and keen. Tom Musatto has a more elaborate system that I am certain works just as well, but this is what works more than good enough for me. When I resharpen in the field I just use the Grizzly file and that seems to do the job just as well, so maybe going for that 'shave me bald like a twinky' edge before the serration stroke is over kill.
