Can't make the linked solutions today. Have VOICE MAIL AND TOMMY COOPER but don't know how to put WAFER, TRIP, CUTTER and GEAR together. Have I made a mistake somewhere
I've heard "cookie cutter" used to mean "reproduce something to the same pattern with minor change of detail", usually in a financial product sense. So I guess "wafer cutter" is roughly the same.
"Trip gear" does not ring any bells. Is it a bit like "trip switch"?
