BTW - for the folks a little scared of self sharpening, water/whet stones, etc...google around and find a place that sharpens or ask a local restaurant who sharpens.
I drop mine off on the way to work to a place, and pick them up on the way home. They record angles/etc...at ~5$ a knife. I do it myself on my Norton stones every once in a while, but can't pull a wire like the pros do, and it's worth it for me to take my 3-4 knives to get sharpened, say...once a month.
