When I was in Junior High School (Grades 7-9) in the US Midwest they still allowed paddling. This was around 1969-1972. I think it was limited to three swats maximum.
Most of the male teachers did it themselves. The women sent them to the Asst Principal who was a former boxer with a cauliflower ear. Despite his appearance he was actually a very nice guy and didn't put full effort into his swats. The shop teacher did make paddles for the women teachers, but they just hung on the wall as a symbol of authority, but were never used.
I had my share of these until the day I was acting up in band class. I think it was for throwing a paper plane out the window. The band teacher told me to come up front for my punishment but as he was getting his paddle off the wall he stopped and said "I don't think my paddle is the right one for the job".
My mother was a math teacher at the school and I had to go ask to borrow her paddle. Quite embarrassing to interrupt her class to ask for it.
