Lorenzo Dotti donated this device to me in August 2006. He purchased it in Italy in the 1980s
The Kong is made from plated steel. The plate is not flat; instead, it has a slight bend to it. It has two long slots that give less friction than standard "Sticht" plates do. Although I don't like this for rock climbing, on snow and ice I don't mind it as much since I'm usually working with two ropes. The slot length is closer to that of various guide devices such as the Kong Gi-gi, and Cassin #217.
