Are you sure you've actually wire edged a blade? to test lightly run a pin toward the edge, should feel a wire edge. The fact that a shave starts out good doesn't really say "wire edge to me" because they would be unpleasant from the start.

I believe the current thinking is that it's actually very hard to "Overhone" a blade, I've never managed it and on my early attempts to hone i certainly went at it for many many strokes.

To speculate, is it not more likely that the either the bevel was not fully set (i use a combo of TNT, MMT and a loupe to establish a bevel is set), or that not enough work has been done on each grit level going up and the scratches from the bevel set have not been properly polished out?
