Big.Dave said:Good point but if that is the case why do we do multiple passes to get a good shave?IanM said:I would imagine that the blade is very close to, or even gliding across the surface of the skin. This will also position it close to the base of the hair. I would think that the where the hair exits the skin, and is supported by it, there isn't really anything to bend, as the cutting is done close to the base of the hair. If this is the case, then there is a definite advantage to the hair being soft, else the blade is going to pull it instead of cutting it.

Because if we were cutting that close to the base of the hair we would only need to do one pass.
Maybe, but shavers rarely repeat a pass, ie-they'll only do 1 WTG, 1 XTG 1 ATG. The need for the variation in the pass directions is owing to the variation of the beard growth patterns.
My initial theory is based on my mental picture of what happens during a shave. I could be completely wrong. All I know for definite is, the wetter and softer my beard is, the easier it is for me to get an acceptable shave.
