hi, i'm new to this forum
but i have been doing carpentry and furniture repairs for a couple of years now, and cant stand blunt tools, especially when wood turning, and i have always used more or less this technic to keep them sharp, it practically costs me nothing as i get alot of free off cuts of beech and oak from the frame makers we use, and i buy sand paper in 20 meter rolls which are relatively cheap if you use it alot
what i have found though is that you generally dont need to strop the blade, if you sharpen against the sharp edge as described at the start of this thread and dont apply to much pressure the burr is usual minimal, but the way i get rid of it, is to run my thumb over the edge of the blade away from the spine (i hope that makes sense) and if you do it on both sides you can feel a slight resistance on one side where the burr is, then run that side on the sand paper very lightly and recheck, and eventually you get to a point where there is no burr on either side, by doing this i have managed to sharpen an old british army knife to the point were it will shave my arm, using only a 7 inch long piece wood and a piece of 240 and 400 grit paper
also in response to the post about cutting through the paper, that generally happens if the angle and pressure is slightly to high, or if the paper is loose, if find it helps to glue the paper to the piece of wood with a thin smear of well spread out wood glue, and then clamped over night with a piece of soft plyboard to get it smooth, i find these last much longer without getting cut,
hope that doesnt sound like i'm trying to boast or anything, i just love sharpening a knife, i find it very gratifying, almost to the point were i probably abuse them a little more than neccessary so i have to sharpen them again
cheers
