Thread title says it all. I like sharp knives and I keep my cheapo kitchen blades pretty good with that $3 yellow keychain gadget you find near the checkout at Lowe's Depot, etc. But I want to expand my capabilities somewhat and do all my pocket knives, scissors, garden tools, etc. And I want to do it using electricity, noise, sparks and foolproof guides that require MINIMAL thought, skill, elbow-grease or time. I'm getting older and I'm not inclined to spend the rest of my life hacking away at things with dull implements. A buddy told me about the Worksharp blade sharpening tool, and went on to tell me they also have a special Ken Onion edition. Both a bit pricey, but I can pony up a few bucks if everything I use from this point forward makes me pause and say "Damn, that's a sharp blade!" Is there a distinct advantage to owning either one of these tools? Perhaps there's something similar I've not found yet? What do you guys and gals recommend?
