A hand-carried toolbox is one of the simplest items to move, but a box packed solid with sockets and wrenches can quietly become a 60 pound load. The job is mostly about sorting weight and latching everything down.
Pro tip: Snap a phone photo of an organized tray before you dump it into a moving box, so refilling takes minutes instead of guesswork.
Watch out: An overloaded toolbox is deceptively heavy for its size; a full metal box can weigh more than a small filing cabinet.
