good information, thanks for that.
i've found that since i got a belt sander i get a little impatient when i'm away from the shop sharpening something.
i also find that since i started sharpening for other people i tend to not want to spend as much time sharpening my own stuff. i still enjoy putting a wicked edge on a nice piece of steel, but doing so much makes me a little bit less giddy about it.
i like to use a belt sander with different grit belts to set the bevel and then polish it, followed by a cardboard wheel loaded with tripoli and then a handstrop to remove the last of the burr. this method works efficiently for doing batches of knives, because i can set the bevels on all the knives, then change belts and polish them all to a certain grit, and so on. if i forget one knife and have to go through all the belts for it, that's annoying to me.
anyways, nice write up. time is a factor in sharpening as well as anything, and one reason that people pay other people to sharpen their knives. some people could learn to themselves, but for the time they would have to invest, they would rather just have someone else do it for them.
