The seed for the Sven-Saw was planted in 1960 on a portage between Knife Lake and Carp Lake in the Boundary Waters Canoe Area Wilderness on the Minnesota-Canadian border. 

By 1961, Richard had made one — the compact folding saw with a blade protected by its handle. He patented the design and founded Swen Products. The company continues to be family-owned and operated to this day, and the parts are proudly manufactured and packaged in Minnesota.
