The Tide is a multifunctional EDC worry coin with a kinetic twist. The Tide Coin has 2 main functions of motion. First, its main purpose is to click. Think of a socket wrench. Inside the Tide are 4 steel balls held in place by small springs. These springs push the balls down into a machined groove. As the top rotates, these balls hit sections in the groove that are wide enough for the ball to travel downward, making a slight clicking noise. You can also slightly feel when that happens. The Tide also features an internal R188 bearing that helps add stability to the click function but also allows it to be a spinner. If you remove the balls and springs from the inside of the unit, it will then be able to spin freely.
