designer's own words:This product started from two main purposes. First, whenever you wash your dishes, you might have difficulty to find spoon as cutlery sink deep down into water. Second, it is based on the idea of easy to hold from a table. Making empty inside helps to rise to the surface when it's in the sink. This is like a float. The thickness gradually reduces on the convex surface of the sphere and the handle which in turn increases the amount of air or EPS. Drop of intensity on the handle is prevented by enlarging the grip diameter. Spherical shape in the center acts as a supporter when using fork or knife to help cutting and chopping with less effort.
