I am with twodog max: I have stopped using my Lansky systems in favor of the Work Sharp Precision Adjust.
Precision Adjust™ Knife Sharpener
– Work Sharp
(And I didn't pay anywhere near $70 for mine - keep an eye out for Black Friday sales coming up, eh?)
My experience has been that there's always some "better" system out there - and I have dozens of friends who'll tell me about theirs. Hey, I'm a retired lawyer: I don't need to impress anyone with a one-molecule-thick edge; I just need sharp knives.
And - while I have many pocket knives - the use this sucker gets most often is on the kitchen knives. It does a great job - restoring the edges to "shaving sharp" in just a couple minutes total (including unpacking the sharpener box, assembling it, using it, and repacking everything) - with the caveat that I strop on a piece of denim from some long-ago jeans when I'm done with the polishing step.
I use this sucker about once a month and I'm glad to have it - it's SO much simpler and quicker than what I did previously. But it might not be right for you - and there are dozens of other great systems out there.
Note that you'll have to figure out the edge angle on any given knife (I write them down on the box so that I can skip this step the next time), but that doesn't take a lot of time. Also, this particular sharpener only has two "stone" grits and one polisher, so it's more of a "touch up" sharpener and not so much what you'd want to change a blade angle. But the infinite edge gradation is a whole lot nicer than the limited choices in the Lansky sets I'd used before and - I'm looking for fast utility, not pursuing the hobby of The Immaculate Blade Edge.
