A typical example of a crook handled secondary school cane might be about 32″ long and 10mm in dimeter. It would be possible to flex it and bend it to a fair degree without it splitting. The tip was sanded to avoid cutting when it was used. Some canes could split or become “hairy” at the end and had to be replaced.
For someone who wrote two days ago that you had never seen or felt a cane, you seem to have lots of information to impart. Much, but not all, of it is correct.
