Bakeware, Tableware, Drinkware and Cookware Design Iedde Mussel Knife by Giuliano Ricciardi The Grammella, a tool used to shell Taranto black mussels, is a typical object of Taranto, Italy. Iedde is the result of a redesign operation focused on the analysis of the traditional tool, its use, the historic and geographic context and mussel. The ergonomics of the tool derives from the handle, whose shapes lend themselves to being received in the palm and from the blade that arises spontaneously following the curve of the grip, to connect harmoniously to the base. This makes the tool easy and comfortable to handle. Iedde is an iconic tool that represents the maritime culture of the city.
