well .... if the rod were threaded, Mr Recaro would have less money to purchase more vacation cottages .........

and then someone would be forced to thread the knob on - instead of pushing it on .......... consuming ten more seconds ........ and causing the accountants ..... industrial engineers ....... on up to the executives to lose sleep over this terribly unproductive process ...........
