Yvon Chouinard and Tom Frost teamed with C.A.M.P in the 1960s to market axes under the Chouinard–Frost name. In 1977 Chouinard ended his partnership with Frost & and took his name off the pick. Chouinard reportedly ended wooden shafts in 1978/1979 but C.A.M.P. continued to list the Chouinard axe (without the Chouinard and Interalp stamps) in their catalog as late as 1983.

Denis Pivot of C.A.M.P. provided the following information on C.A.M.P.'s relationships with other manufacturers:

CAMP - Chouinard

In 1968, during a trip to Italy to participate in the Trento Mountain Film Festival, Yvon Chouinard visited the CAMP factory in Premana with Hermann Huber (Salewa). Following this visit, an agreement was reached for CAMP to manufacture ice axes, pitons, Hexentrics and Stoppers for Chouinard (later Black Diamond). This equipment was sold by CAMP with the double marking of the logos CHOUINARD and CAMP and the addition of the logo of the INTERALP sales agent. All Chouinard equipment marked "Made in Italy" or "Italy" was manufactured by CAMP.
