This is assuming though that brittle is the opposite of hard?
From and engineering point of view, i would say whiskers are tough, that is resistance to impact as opposed to hard, which is resistance to deformation. Increasing the brittleness through cold water shave is the same as make the whiskers less "tough", ie it is easier to cut them. although they can remain hard. Although strictly in the case of cold water we should say "makes it easier to fracture them.
So not necssarily more destructive to the edge as it takes a lot less force and effort to effectuvely fracture the hair than to cut it if it were a dry shave.
In the case of warm water shaves, my hypothesis is that through the action of lather, water and heat, you soften the hair, decreasing its hardness thereby increasing its "cleavage" which is its capacity to be cut.
as i said, these are just my hypotheses on the subject
and i may have my terminology wrong, but i know what I'm trying to get at uni was a while ago
Edit: I pretty sure ductility needs a mention in the warm lather shave hypothesis.. Will have a think, goes hand in hand with cleavage anyway, and cleavage maybe an outdated termLast edited by tekbow; 06-26-2011 at 06:44 PM.

Ah, but the lathering is a significant part of the entire shaving experience which adds to the stropping, the shave itself and finally the aftershave and becomes greater than the sum of its parts. I wouldn't enjoy the experience nearly as much without it.

Excellent! Thanks for all the ideas as to what's going on. I'm merely a humble chemist, so unless we're talking about shaving with harsh chemicals, I'm flying by the seat of my solvent soaked pants!
