If your little builders inherited the DIY gene, then they're more or less programmed to dive into Mom and Dad's tools. So maybe you should think about giving them their own set. This toolbox is just the thing to hold smaller, basic items that fit a young do-it-yourselfer's hands, including a hammer, saws, pliers, and screwdrivers. Building it is easy: The tools required are probably already in your stash, and the materials are readily available at a home center and a sporting goods store.
