The Machine Era Co. KeySquare ($38) is a new way to carry your keys, and open bottles while getting something handmade, designed, and machined in the USA. The KeySquare will be one of your favorite everyday carry pieces. The slot, with its belt loop stay, is designed to hold securely to your belt loop, while being easy to detach. Each piece is nickel plated and made from a solid block of steel, which creates a stronger, more reliable product. Because these are in such high demand, please allow about a week for shipping.
