A TV show called "Ask This Old House" (PBS.org) has a segment in which they have a curious household or tool gizmo. One person knows what it is, but asks the other guys to guess and they all tell tall tales about its purpose. Well I found a gadget while junking this last weekend because the hubby was looking for some cheap camo clothes.
It's wooden, slides forward and back, looks like it has a long metal needle at the end and is labeled "TRU-GYDE by Wilson Brothers, Springfield, Missouri." I think I know what it's for, but can you guess?
