watch those tutorials on how to sharpen convex edges. Very easy to do once you get the hang.
All you need are various grits of sand paper. a cheap computer mouse pad, and some leather and buffing compound. I have used cheap buffing compound from the hard ware store to load my strop (which I made my self).
Warning, however, watch the tutorials several times, and practice on a cheap knife or two first before jumping in on the Infi.
It really is not too hard, and you will find that many many hogs prefer a convexed edge for the simple ease of maintaining it.
Biggest thing is not to press hard at all. A light touch is what is needed.
The sharpening systems are great too. But as you saw from pricing them they are costly. Also, learning to sharpen free hand is a skill that you can use without any system. If you have a basic understanding with free hand sharpening methods, you can toss a crock stick, or some sand paper and piece of loaded leather in your bag for camping etc.
the polishing compound at bark river is a good choice. (but like I said, I use cheap stuff that works ok, just not as fine of a polish
I made a 4 sided strop out of a broken belt, and a piece of wood.
After a bit of stropping.
I actually only use the #6 buffing compound (which is in the red topped container, but the stuff is actually green).
All my infi has convexed edges now. It is not better than a v-edge. A sharp v-edge will cut the same as a convex edge. You can have a dull convex or dull v edge. Thick or thin for either.
either type of edge will either be great or suck (according to your skill). The great thing about a fixed sharpening system, is it takes the guess work out. I used one for the better part of my sharpening career, and have only in the past 4 years or so started moving to a convex edge on all my knives (all my users at least).
The advice about the steel rod was good stuff as well. I use a smooth screw driver whenever I damage my edge. I try to align the edge as much as I can first with the steel, before sharpening it, which will save you from removing any more steel than you have to.
As others have said already, hand out on the maintenance forum and learn what you can there. Watch as many tutorials as you can on the subject.
If all else fails and you mess up your edge, you can always send it in to Busse and they will sharpen it for you.
Good luck.
