I guess it keeps the engineers busy, inventing new things that are supposedly "better", but not really. Maybe it's cheaper to mold it out of plastic and put a ratchet mechanism inside? (I'd still like to know why that's necessary) But now you have to pay for the injection molds, plus all that design labor. So you raise the price to pay for that. Bottom line is, some bean-counter, somewhere approved it, so must make sense. :rolleyes:
