Ever notice how a trusty old pocketknife can solve more problems than most folks

Ever notice how a trusty old pocketknife can solve more problems than most folks give it credit for? Found mine at the bottom of the junk drawer this morning. Thought it was long gone, but there it was, ready for duty. Cut some baling twine, whittled a bit waiting on chores to get done—just like an old friend you didn't know you missed till they showed up. What's that one tool you wouldn't trade for all the modern gizmos in the world?
