Designed to fit naturally in the hand, the gently swooping curves of this stainless-steel cutlery service make each piece as pleasurable to hold as it is to behold. In spite of its unique design, each piece feels strangely familiar and combines well with a wide variety of Iittala bowls and serving trays. Dimensions: 10.5" Material: Stainless steel with wood handles Renzo Piano founded Piano Design and soon became one of the most important architects of the 20th century. His eye-catching projects include the Centre Pompidou in Paris, San Nicaola Stadium in Bari and Kansai International Airport in Osaka. His many prestigious prizes and awards include the Compasso dOro, the Pritzker Prize, the Erasmus Prize and the Kyoto award, to name a few. Iittala cutlery is made of austenic, rustproof 18/10 steel, which consists of 18 % chromium and 10 % nickel. Chromium protects the steel against corrosion. The addition of nickel to the alloy increases its corrosion resistance while adding a bright polished appearance, hardness, and exceptional resistance to all temperatures. Iittala cutlery is either polished or matt-brushed. Polishing guarantees a shiny surface and rust resistance. The mat-brushed cutlery is first polished in order to improve the rust resistance, then brushed mat and washed. Stainless steel is a very durable material. However, under certain circumstances it may rust. A material that is completely resistant to rust has not yet been found. Therefore its important that you take good care of your Iittala stainless steel cutlery. Wash, or at least rinse, the cutlery immediately after dining. Do not soak the cutlery for a long time, and do not use steel wool for cleaning. If you wash the cutlery in the dishwasher, the cutlery basket should not be packed too full and the blades and spoons should have some space between them. When the cutlery is left in the machine after washing, open the hatch. Humidity is not good for the cutlery. Vinegar, mustard, mayonnaise, rhubarb, and salt can leave tiny, dark spots, or even rust, on the surface of the cutlery if it is not rinsed or washed after use. Even though the cutlery is very durable, it may become scratched, discolored or worn with time. You can make old cutlery shiny again by doing the following: Boil 1 liter of water and add 1 dl of washing powder. Boil the cutlery in the mixture for 15 minutes and rinse properly afterwards. Sometimes the stains are especially hard to remove. If this is the case, use a vinegar-solution of 1 dl vinegar and 1 l water.
