I don't think its a matter of wedges being cheaper because though they use more steel the labor is cheaper because it takes more skill to grind a double hollow grind which means more time and time is money. At any rate the pearlduck Satinwedge is a small light wedge anyway. I thing its more style and the idea of a more modern razor. Also the wedge is more difficult to maintain.
Who knows, all the players are now dead so we have to guess why one succeeded the other.
