Grabbing your toolbox and tackling a few repairs around the house can certainly teach you some new and useful skills. But if you really want to better yourself, and increase your brain power, you'll reach for these lovely toolbox chess sets instead.
Made by a pair of Etsy sellers who also happen to be father and son (awww) the playing pieces in each set are actually made from powder-coated nuts, bolts, and other hardware you'd find in a real toolbox. At $US245, available in red or black boxes, it will probably inspire you to hunt down your own toolbox and save a pile of money by just making your own. [Etsy via DudeIWantThat]
