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 & Black Diamond

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, through 1980, the additionale logo of the INTERALP sales agent. All Chouinard equipment marked "Made in Italy" or "Italy" was manufactured by CAMP.

First appearing in 1972, Chouinard’s Climaxe was his response to the Terrordactyl, with the curved rather than the drooped pick being his choice. It was created with help from his friend and fellow climber, Tom Frost.The 1972 CHouinard catalog described it as follows:

The ultimate technique on steepening ice, before resorting to artificial climbing or chopping steps, is front pointing using two Alpine Hammers. Rather than each man having to carry two hammers we have designed a mini-axe with the same pick as the Alpine Hammer but having an adze for cutting "pigeon hole" steps in extremely steep ice or for clearing away verglas on rock climbs. This combination of axe and Alpine Hammer is perfect on near vertical ice. The Climaxe is so versatile that it can also replace the more cumbersome ice axe on some mixed climbs.

The 1972 C.A.M.P. catalog lists two handle options, ash and bamboo, but lists only ash in 1976. The 1972 and 1976 Chouinard catalogs do not list handle options or specify the wood used.
