Carl Pott got the idea for this design while sitting under a chestnut tree and watching a leaf fall. The organic shape became the inspiration for the spoon, and the other flatware pieces were derived from it.
The double-edged knife has less to do with nature and more with actual usage. The serration on the backside of the knife is ideal for carving into a piece of meat, while the other side is perfect for actual slicing.
As the flatware of the 1972 Munich Olympics, the design became world famous.
