I'm all for corporal punishment, got it then and give it now, but that rod looks a little excessive.
A parent should never use a hand. Hands are for hugging. It's hard to find a good spanking implement. You want something that will sting, but not bruise or injure. You want something with a long enough handle to allow the parent to get a real swat properly aimed so that it doesn't hit the leg or back. And you want something that is known as the instrument of instruction. We used to put rods in every room of the house so we were prepared to go through our discipline ritual as needed.
