I figured this was a topic beaten like dead cattle for years and never brought it up myself- So, I did a lot of reading- there's thousands of posts on BF about this and it's pretty much like going car shopping - it becomes a blurr and bottom line is- spend more than you planned.
I've bought a couple things- The Ken Onion Worksharp - cool little belt sander, love all the belts and all but the angle guide to me was worthless when you lay and 8" or bigger blade on it and it put marks across one of my CS blades and it's pissed me off since because I'm too stupid to know what to do to get them out without making things worse *which is my forte'*
I looked at the WE systems, read a lot of pro's and cons and it's not perfect. So I went with a Lansky/diamond hones and bought additional diamonds and hones up to 2000 (really just wanted the hones) the whole angle guide thing looks to be about $3 quality level. I Read a lot on strops and decided to can those ideas and learn how to do it with diamonds and hard stones.
Put it this way - I've always sucked at sharpening because no one ever taught me that knew what they were doing, just the average "Dunk Uncle Jack of all trades but sucks at most of them" kind of pathway - I sharped a couple up a few weeks back and were so sharp I dulled them back just a fuzz because if someone picked it up like we do, and gotta feel that edge, you're already cut deep - So pretty damn proud of that for a newby - but it's scary what a few buck can accomplish with the right tools.
