Once the pitons were marked "Stubai," another stamp was added to the pitons "CMV" which stands for CrMoV steel, or Chrom-Molybdenum steel. But for some reason some of the pitons are stamped "CVM." (?)
None of the Stubai catalogs shown have year dates on them. I did the best I could to place the year with the pitons.
The Stubai products were eventually distributed in America through Omni International Distributors located in New York. At some time a Omni piton was created. I am not sure what company created the Omni piton or if it is a Stubai made product.
