I have done the Wire edge before and not noticed it till I actually chopped something.
I definately keep my edge closer to factory edge angles. I have some convex edges that are probably less than factory, but it seems the convex edge supports its self better tan the same angle V edge does.
I know people like to take their edges down under 20 or 15 per side, but with most steels I own, I find the edge does not last as long, and is a bit more prone to damage (with all the different steels I have used).
The funny thing, is one of the knives i Keep at a pretty thin grind, is a hand made 5160 I heat treated in my back yard, and it has out performed my expectations for such a thin grind. I must have left it a bit harder on the heat treat and temper.
