Tool Chess was invented around the time the family business -- a machine tool business based in Grand Rapids, Michigan called Gallmeyer and Livingston -- was closing down. A couple shop workers replaced a lost chess piece with some hardware pieces and my grandpa thought up the name "Tool Chess." My dad sold a few sets about ten years ago, but since then the project has sat dormant. Like a phoenix rising from the ashes, Tool Chess is back! Tool Chess sets are gorgeous, handmade chess sets made out of nuts and bolts. They are powdercoated to give them a lasting, durable finish. Ogle our pics at www.etsy.com/shop/toolchess. Thanks!
