I like the various angle aligners a lot. They really helped me figure out how to identify and maintain a good bevel. I also discovered that for me, it's much easier to keep the blade steady and move the stone across it than to try to free hand a blade across the stone.
I think that's why all of the "pro" systems (e.g., Wicked Edge, EdgePro, KME, etc.) all use a clamp to hold the blade and stones that move across it.
Stropping of course you do blade in hand, but since you're dragging the flat of the blade towards the edge, it's easier to maintain the angle.
Really, that's all you need. I just like it when you can almost feel an "aura" coming off a knife, because its so sharp. I suspect that before I was an OCD Quartermaster in a past life, I was some kind of sharp instrument maker - because I really like sharp things.As soon as I'm shaving hair off one of my limbs, I call it good. This sounds really sharp!
