Riccardo Cassin was an Italian mountaineer. Cassin began designing and producing mountaineering equipment in Lecco in 1947 when he produced his first rock pitons. In 1948 he produced his first hammers; his first ice axes appeared in 1949; and 1950 saw the introduction of his carabiners. Located near C.A.M.P., he worked closely with, but separately from them. C.A.M.P. acquired the Cassin trademark in 1997.
