Yvon Chouinard bought a second-hand coal-fired forge in 1957, and started making hardened steel pitons under the Great Pacific Iron Works name. Their success led him to form Chouinard Equipment, Ltd. He partnered with Tom Frost, and they moved their operation to Ventura California in 1967. The Chouinard product line expanded into a wade variety of climbing and related outdoor gear. In 1971-1972, they introduced Hexentrics and Stoppers. Frost left the operation in 1977, and his name was removed from ice axes and other products that had born the CBouinard-Frost name.

In 1968, during a trip to Italy to participate in the Trento Mountain Film Festival, 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 (and 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.

In 1989, Chouinard Equipment was facing a liability lawsuit. Chouinard had to separate the liability of Chouinard Equipment from the deep pockets of Patagonia, which he had founded in 1973. Chouinard Equipment filed for Chapter 11 bankruptcy to protect the firm's assets. The lawsuit ultimately went nowhere. Peter Metcalf, Maria Cranor and former Chouinard Equipment employees purchased the company assets in 1989, formed Black Diamond Equipment Ltd., and moved the firm to Salt Lake City Utah.
