This may be one of the most indestructable clipboards ever made. The board is made from a 1/16" thick piece of carbon fiber. As you can see in the last picture, that was thick enough to support my entire body weight. Instead of riveting the clip onto the board like you usually see, I decided to use an aerospace grade film adhesive to attach it. I'm pretty sure the clip will break before the adhesive fails.
*** Because I work in the aerospace industry, some of the materials used in this project may not be as readily available for others as they were for me.***
