=== Saf-Ski—1937 ===
[[Hjalmar Hvam]] broke his leg skiing, and while recuperating from surgery, invented the Saf-Ski toe binding in 1937, which he later sold under the slogan "Hvoom with Hvam".<ref>{{Cite web|last=Byrne|first=Michael|date=September 2, 2016|title=Gear Physics: The Leg-Saving Brilliance of Skis That Let Go|url=https://www.vice.com/en/article/gear-physics-releasable-ski-bindings/|access-date=2020-12-23|website=Vice.com|language=en}}</ref> This was a metal clip with a pyramidal top that fit into a slot cut into the sole of the ski boot. When the boot was rotated forward, the slot on the toe eventually rose above the metal pyramid, allowing the toe to release from the ski. The system was considered with suspicion by professional skiers, especially when Olaf Rodegaard released during a race. However, Rodegaard credited the release with saving him from a broken leg.<ref name=":6" /> In the post-war era, Hvam sold several thousand pairs of Saf-Skis, in an era when alpine skiing was in its infancy. Hvam continued to sell the Saf-Ski into the 1960s, but in 1966 his insurance rates increased so dramatically that he was forced from the market.<ref name=":6" />
