The cane, slipper and other implements were used in my school. The poor recipient of the cane had to go and get the punishment book and walk it to the Dep Head, receive the beating and then walk it back. Never bloody worked and it was always the same boys receiving it. Even as a kid i never liked nor trusted the teachers involved in it, it was just plain brutal. Some of the teachers would use a plimsoll without so much as a by your leave. I remember one lad being chased around the gym by an enraged teacher as he was lashing out at him. It wasn't illegal, so no retrospective court cases.
Today it would quite rightly be seen as abuse.
I should add that some of the younger (less than 40 year old) teachers at our school did not believe in it and would not issue a punishment that would result in a child being caned.
This was 76 - 81, the beatings ended in 86 when the Government banned it in any school that received any state funding. Private school children had to wait until 98 for similar protection.
I think it is shameful it took so long to end.
