The principle had a barber’s razor sharpener.
Not kidding.
Our principal had the “board of education.” Never mind the leather strop. The lettermen’s club required inductees make a wooden paddle as part of initiation, that was then given to their upper class sponsor. Occasionally the principal inherited one of those paddles which was occasionally used on miscreants. Wrist action is key. One could hear the POP clear down the hall.
