In the much ballyhooed Verhoven paper, he does an experiment in regards to edge first, or edge trailing, and found much better results with edge leading honing. The theory is that the edge "sees" only the hone that removes the metal from the edge cleanly, and all the debris of the honing process therefore exits to the back of the blade.
When done with the edge trailing, all of the crap that gets honed off of the bevel before it gets to the cutting edge gets shmooshed under there and mucks things up.
Verhoven didn't use highly technical phrases suich as "shmooshin", and "mucked up", but I'm an engineer dagnabbit, and I gotta use phrases such as that to make me sound high-falooting.
I will also say that I don't hold anything that a barber says in any more regard than what anyone else says, and perhaps even less so, as these guys are expert at slinging the B.S. all day long.
Sort of like us here at SRP!
