This innovative tool from Zyliss both cuts and serves cake using just one hand. A serrated stainless blade cuts the cake, and since it's serrated on both sides, the blade works for both right and left-handers. The moveable plastic blade on top then slides forward with thumb pressure to deliver a slice of cake to a plate. The blades come apart for cleaning and it's all dishwasher safe. 11.5" x 3".
