2.- A...

Sorry, I am not a math geek (though I understand what you say). I...

Because the edge has a smile and second, because the blade rockets on the hone, hence the need for the "exotic" sharpening strokes.

I was talking theoretically, of course!

I have an old W&B with a smile and when I put it on the hone, 95% of the edge makes contact at the same time.... Of course manufacture slight deformations,...

I am sorry but that statement is wrong. You are seeing the blade as a single plane.

A curve is made of interjections of lines at different angles. The same applies when talking to planes. A curved...

Yes, I have seen the wiki on the rolling X strokes, thanks.

I will do that and I will let you know how it goes :)

The problem is not a warped edge (for the moment) but that the spine is not straight and the blade does not fully sit on the hone because of the spine (to see pictures).
