Good Eatin': A Thorough, Not-to-Say Obsessive, Intro to Knife Sharpening

There's so much, so very, very much you don't know, Grasshopper:
"Knife sharpening is not difficult. It is not shrouded in mystery. With a little knowledge, a little geometry, a couple of tricks and some inexpensive tools, knife sharpening can be fairly easy and extremely rewarding. At the very least it’s a great skill for the toolbox. You’ll come away from this clinic with a better understanding of edges, steel and how to maintain your knives yourself. Or, if you decide to send them out, you’ll know how to make sure you’re getting what you want – and what you pay for." -- from the website of the eGullet Culinary Institute.
