While Sason received job offers from Detroit’s “Big Three” automakers, he always declined because he struggled with the English language. In addition to his work with Saab, Sason opened his own design firm, Sixten Sason AB, and he flourished as an interdisciplinary industrial designer working for some of Sweden’s biggest companies. Victor Hasselblad approached Sason about creating the world’s first single-lens reflex medium-format camera with interchangeable lenses and magazines. During the war, Swedish intelligence agents had brought Hasselblad an impressively powerful aerial camera recovered from a downed German plane, and Hasselblad wanted Sason to design a civilian version, which debuted in October 1948 as the iconic Hasselblad 1600F. For Electrolux, Sason designed handsomely futuristic vacuum cleaners, floor polishers, and kitchen mixers, and for Husqvarna, Sason designed the company’s first chainsaw, its first “zig-zag” sewing machine, a line of charmingly simple clothing irons, and the most remarkably attractive waffle iron to ever exist. He also penned the Husqvarna Silverpilen, or “Silver Arrow,” a small, lightweight, 175cc two-stroke motorcycle introduced in 1955.
