Before I got into knives (other than the kitchen kind), I had and still have some waterstones that I used to sharpen chisels and plane blades. There are guides, I have them. The stones need maintenance to keep them flat, so more stuff. Was never an expert, but got some good results. Problem was, woodwoorking tools need a lot of regular maintenance, so most people who do it regularly have dedicated sharpening stations set up. I never did, and I was (and still am) behind on maintaining those tools, so to sharpen one of them pretty much meant a time consuming effort starting from scratch. I then read about using plate glass and automotive wet/dry sandpaper - cheap and pretty easy, very low maintenance, with a big surface for plane blades and such. Not as hard technique-wise. I bought a DMT aligner setup for doing kitchen knives, and was soon using it on my collection of folders as well. Easy to use for beginners, effective for the more advanced. Then, I got a BK-2. Didn't fit in the DMT clamp, and since it was in need of sharpening, I gave it a go on the waterstones, with pretty good results, but it took a while. Then I chipped the edge a little, and didn't want to spend an afternoon working it on the stones. I started reading about the Worksharp here on BF and finally bought one this past spring. Turns out I had a ton of other knives, tools and garden implements that needed help and I had been ignoring, because I didn't want to spend a week taking care of all of them.
Bottom line is the Worksharp kind of changed my life, because it made the onerous task of maintaining a house full of tools and knives doable. I realize that while I like mirror polished edges, I want to spend my time using my knives, not sharpening them. Whatever you end up with, and my guess is you'll end up with a couple of different systems eventually, it should be fairly easy to use and set up, so you can maintain your edges. There have been a lot of good suggestions here, which I'm sure work great. I'll come down in the Worksharp camp. I won't discard any of my other systems; the DMT is field portable and easy to use for thinner blades, and the WS doesn't work for chisels. Hell, I could probably get by with wet/dry and wood blocks. I'll still use the WS more often, for more different stuff than the other methods. For me, it's easy and takes very little time, which means more time do the fun stuff.
For anybody who read this all the way through, I'm sorry. Longest. post. ever.
