I am with the freehand advocates - after I learned to sharpen freehand, especially after I got some good stones and nice strops, I never used my jig systems again.
The point is, most systems, including freehand, work well once you learn them.
I've seen enough very well sharpened freehand knives to know that some folks can learn to do it. Personally, I like the Edge-Pro. Others like power tools. I suppose, that given enough practice, one could learn to use any method more or less effectively.
What frustrates me most with the "freehanders" is their arrogance, (most of them,
not all by any means) and their attidude that
"real" knifeknuts freehand only, and they look down their noses at anyone who uses any other system.
Michealangelo once said that sculpting was easy. You just take a piece of marble and chisel away anything that doesn't look like what you want to create. Perhaps there are other people who can do this. But just as not everyone could carve a "David" or a "Pieta" from marble, many cannot learn to "freehand" or use power equipment as effectively as some other system.
Most of us that are serious sharpeners have tried all, or almost all, systems and settled on the one we're most comfortable and slilled with.
So long as the end result is the same, what difference (other than snob appeal) does it make which system you used???
