Cardboard is where it's at!

I just started stropping a little while ago, and I've been stropping with the entire knife almost flat (but not quite) to the strop-keeping it raised 10 degrees or so just so I don't get the belly of the blade worn and scratched. I don't need a full convex, I just like to keep the shoulders between the belly and primary grind and primary grind and secondary grind a lot less pronounced, plus stropping like this is honing/polishing/straightening the edge out. I had been doing it on leather with a heavy metal polishing compound, but I tried some cardboard tonight and it seems to work a LOT better. I don't think it conforms as well to the edge contour, but the coardboard seems to get the edge a lot nicer. I think my new edge maintenance is going to be more frequent touchups instead of less frequent major sharpenings.

Tonight I passed the edge over the 20 degree edge setting on my Sharpmaker with just the corners and flats of the fine (white) rods, then I stropped on the cardboard. It worked great!! You can see where the edge shoulder is becoming less defined so it won't wedge up. By the time I was done with the loaded compound and put a few passes down on dry coardboard, my knife could easily slice a very old, very ragged and soft receipt. I can shave with it if the edge touches my skin, but I can't shave from middle or top of the hair. Any tips on finer stropping? :confused:

Don't rely on the cardboard to raise the sharpness, it should be next to ideal off of the stones. Cardboard is a very mild abrasive and can do little to minimize the burr on an already well formed edge. Have the edge as best as possible from the stones and use some very fine polishing compound on the cardboard, 0.5 micron or similar to increase the polish. It will take a very high level of sharpness to shave above the skin unless the edge angle is very acute and it can be difficult to obtain that level with some of the softer and more coarse steels.

On your Sharpmaker, go lighter, go slower, and don't use the corners (just the flat sides) unless your knife is serrated or too curvy to use the flats, at least not with the white hones.
