Here are some images to illustrate it all.
I actually really like this image from Best Spanking Pics. The girl is obviously a naughty school girl who has been called to the head's office for six of the best from that fearsome looking cane that is being held in front of her. Canes were often used on the hands. This is something I am strongly against! It is very easy to inadvertently break the small bones in someone's hand with a cane. Nature provided us with the perfect place to receive punishment and that is the bottom. Caning a bottom will definitely hurt, but you won't break it.
Spanking Sarah has given us an excellent picture of a woman receiving a 'sixer' on her bared bottom while bent over. The cane is very traditional here. That red patch should alter into distinct lines and look rather attractive later on.
This image from Spanked At Home illustrates what I was talking about. The strokes aren't quite as defined as they could be. The owner of this bottom will be sporting some rather interesting looking black and blue 'tramlines' in a day or two.
I'm not totally sure what the fascination with the riding crop is all about. They're much better suited to urging horses on than they are for spanking bottoms. Most of the impact is localised in that little tongue of leather at the end. Unlike canes they can be used with the victim otk, although like the cane they're more effective with the recipient bending over or laying prone on a bed or bench.
These final two pictures are from Muir Academy; an institution that specialises in older naughty boys and girls. I do not like the birch. I don't have one and I felt one once, not an experience I would want to repeat, I won't use one either. These two pictures are fairly mild, but this was used as a punishment in prisons and to discipline criminals in days gone by, it was also used in the schoolroom by some rather vicious teachers I'm sure.
I do apologise for this particular entry not being as much fun as others. I think my prejudice against the implements shows out quite strongly. I can't help it.
Maybe the next entry will be more pleasant.
