A toolbox with a sliding handle. To balance an off-center load, you could move the handle along tracks on the top and lock it in the new position. – Joe Burke, Bay Port, mich.
April 1959
The modern-day equivalent would probably be something like this toolbox on Amazon (affiliate link) that simply has a handle that stretches the full length of the toolbox, therefore giving you the option to hold it exactly where you feel it is best balanced.
