The Sigma Touch Tool is a timely instrument for interacting with high-touch surfaces. The fluid brass form is an alluring merger of utility and style—an added layer of protection and a striking artifact of a strange time. As a new way of moving through the world has rapidly emerged, old habits die hard. In order to help mitigate the inadvertent spreading of germs after pressing a button or opening a door, a simple tactile instrument can come in handy. Will this tool alone solve our problems? Certainly not. But when paired with other healthy practices, it has the potential to make a small but meaningful difference. Named for its resemblance to the Greek letter Sigma (∑), the Sigma Touch Tool is machined from solid brass. It features an eyelet for attaching to a keyring, a hooked surface for pulling doors, and a subtle protrusion for use as a stylus and button-pusher.
