In the mid-2000s, Joachim Fiedler was a professional cellist in Germany. A tinkerer by nature, he found himself frustrated by the bow holders inside the lid of a cello case: They were fiddly and required two hands to open, whereas Fiedler wanted to do it one-handed. He thus prototyped and refined a magnetic bow holder. Pressing against a latch released the bow. Despite having played with the Berlin Philharmonic and having toured the world with different orchestras, Fiedler became obsessed with magnetic connections rather than music. In 2007, he hung up the bow and started Fidlock, a company that makes magnetic buckles for bags, helmets, tents, clothes and more.For some examples of the actions, this SNAP pops open at the pull of a strap:This 3-point JUNIOR is for baby carriages:This magnetic ratcheting WINCH is for bags and outdoor gear:This COINTRAP is for bike helmets, and is designed to be easy to use in cold weather, when one is wearing gloves:You can see more of Fidlock's offerings here.
