Hmmmmm 'AI', What is Marwa?
Marwa was not a separate company. The “Marwa” refers to a specific type of carabiner and ice screw. Designed by Sebastian Mariner (often known as “Wastl Mariner”), and produced and sold by Stubai. Stubai was the company that manufactured and marketed the carabiners and ice screws designed by Mariner. |

The REI 1962 catalog shows the Stubai Marwa corkscrew ice screw and the illustration shows the extra curl design (First generation). The catalog does not mention a manufacturer name.

The 1964 Fisher catalog shows the Stubai corkscrew ice screw with only a single curl. So sometime between 1962 and 1964 the design changed.
