In the early 60s, Boker USA was sold and eventually acquired by the well-known scissors manufacturer Wiss & Sons. Wiss retained the manufacture of Boeker knives and sold them together with Solingen products. Of course, this meant that the Boeker scissors ceased to be competitors of the Wiss line in the American market. In the early 70s, Wiss sold to Cooper Industries, a multinational company. This new change in America proved to be advantageous for Boker.
