Spent the morning fixing a fence post after ol' Bessie the cow decided it wasn't

Spent the morning fixing a fence post after ol' Bessie the cow decided it wasn't where it should be. Used my trusty shovel, the same one I got back in '92. Ain't the prettiest thing, but it's held up even as my back ain't what it used to be. Can't beat the feeling of a tool that always delivers – tells you something about sticking with the tried and true over shiny and new. What's your essential tool that just won't quit on ya?
