Hi Bob.
I use a Lansky set which has worked very well indeed for me. It allows me to keep all of my knives very sharp with minimal effort. It took a little bit of practice to get the technique right and to learn to judge edge angles, but once you "get it" it's very straightforward. I have also been looking at the edge pro system which seems like a more expensive, better designed Lansky. When I can justify the outlay I may have to give it a go.
As for testing the edge, like a lot of the members here I have an almost permanently de-forested left arm! If the knife can take the hair off my arm without snagging or pulling then it is sharp enough for me. I've also used the test of shaving strips from a sheet of paper. Usually it's whatever I feel like at the time. You do also develop the knack of "just knowing" when you have reached the correct degree of sharpness. You can kind of see and feel it in your gut. Sounds weird I know, but that's the best way I can think of to explain it.
I'm sure some of the more experienced guys on here will post their methods too. No doubt New Pig Hunter will share his unique method which I have yet to try out.
Hope that helps.
