I've often wondered why straight blades are as long as they are. It seems to me that a shorter blade would simplify shaving of the neck a great deal. Obviously, the tang has to be long enough to accomodate your grip, but why such a long blade? Solingen razors, especially Dovos are especially long in this regard. It also makes stropping and honing more difficult if the blade overhangs by a lot. Any ideas as to what constitutes the ideal blade length and why?
