Lynda70 I can vouch for that. I went to a boys' grammar school in West Essex where the cane was very rarely used - the "nuclear option", if you will. (Apparently the previous Head had been very cane-happy but he retired two years before I got there in 1976.)
However I found out a few years later that our sister girls' grammar a couple of miles away had been very cane-happy right up to abolition.
Likewise, an acquaintance of mine who lived just over the county border, in Hertfordshire, went to a boys' grammar that was also fond of the cane.
It varied a lot.
