First off I think every Traditional bowhunter should learn with just a simple file or at least a big file a finishing stick. The skill will come in handy one day and its just part of it.
After all that is out of the way this is how I sharpen my VPA's out of the package.

Simple as that. If I really mess one up hunting I take it to the big Nicholson to reset the angles and back to the wheelie.
At least a couple sponsors sell them, Simmons Sharks is one I know of, they fit in a pack, and are a whoppin' $9 bucks.
Works on 2,3, and 4 blade heads if the bleeders come off. If the bleeders don't I hit them with a jewel stick.
