Weighing in at 40lb, this all-metal chess set will create a stunning centerpiece for any space. Each set represents over 15 hours of machining time on 5-axis CNC lathes. The 20x20x1 inch board takes over 4 hours to machine from a solid aluminum billet and weighs 30lb by itself. The 'white' pieces are machined from solid brass and brushed lightly. Over time they will develop an attractive patina as the low points darken, and the high points will become shiny with use. The 'black' pieces are machined from solid steel prior to being blackened to a dark blue/black finish, which will also develop into a naturally aged look over the years. All pieces come with vegan suede pads, giving a satisfying metallic thud when the pieces are placed onto the aluminum board. The set shown in these photos has been used for several weeks and shows the set somewhere between its brand-new, and slightly used states. The king measures 3.5 inches in height, and the board uses 1.75-inch squares. Although slightly smaller than the competition size we feel this is just right for at-home play. Each set comes packaged in an aluminum flight case, with CNC-cut foam inserts, beautifully displaying each piece when it's opened.
