Spanking: know your implements!

Spankings hurt, that should go without saying, but many people ask which implement hurts worse?
Which leaves bruises? The answer to that is, they ALL can hurt and each implement has the capacity to leave bruises if you strike hard enough  over a long period of time. This chart however was designed to try adn help give a side by side comparison of different implements.

For the sake of this chart a base of 6 Swats on a bare bottom at full strenght was used as a base.
