That's a 6' folding rule. Here's a few on that, lol. What's the biggest number on it, w/o looking? [not 72]

If you unfold it, stand it on the floor andmake a mark on the wall, it will be at 72" same as 6'. Did you know I/you can cut 11" off of it, and it will still measure the same [stood on floor and reach previous mark]?? W/O using the 11" in any way!! Old carpenters know alot of tricks, lol.
