a pointed tool for marking surfaces or for punching small holes

A stupid person; it refers to the lack of surface area on an individual's brain. The general thought is that the more surface area (wrinkles, creases, etc.) a brain has, the smarter the person is. Conversely, a person with a smooth brain (no wrinkles) has less surface area and would therefore be stupid.

The biggest tool of them all. Because it's the most useless tool in the toolbox.
