I've got a Lansky set-up, basically all the sets apart from the Arkansas stones. With three clamps and two stands you can sharpen just about any length of blade. There are several tricks that you learn, one of the best is once you've got the stones and guides set right, I then leave them set and wrap them in a tool roll that I got for chisels. This makes the set-up a lot quicker.
Is it the perfect system - NO not by a long way, but it works for me. I'd like to try a Lansky or Spyderco crock stick system.
I do have bench stones and diamond paddles that I use between full on re-sharpenings and I have strops as well.
An Edge Pro Apex or Wicked Edge would be nice as well but I can't see that happening any time soon. The Ken Onion version of the Work Sharp looks intriguing as well.
I don't use my knives all that hard and the blade steel on most is 8Cr13MoV or 9Cr18MoV, Enlans, SanRenMus Ganzos mostly so the sharpening is easy.
With a growing collection I can spread the use out over more blades so increasing the time spent between sharpenings.
Now that I've got a workable set-up I'm more likely to spend money on knives than sharpeners. Although Lansky announced semicircular hones for sharpening re-curve blades, I'll have to get some of those, I have at least one Karambit that could do with a sharpen, I was waiting to get a crock stick set but the semicircular hones would do the job.
