The Stinger represents something of a rebirth for Sasaki, who, after a career spent designing protective gear for cycling and other action sports, moved with his wife from San Diego to their second home in Truckee in 2016 (he also started and sold a company that manufactured iPhone cases from exotic materials). Once settled in,<br>he didn’t want to do anything but “ride and fish” for a couple of years.<br><br>After 400 days of fishing, spread out over those two years, Sasaki realized that the only thing he truly wanted to do, work-wise, was improve every piece of fly-fishing gear he owned.<br><br>He started with the reel, aiming to create a device that improved his rod’s efficiency and allowed him to “fish longer and catch more” without adding to the shoulder and back strain common to the sport. Starting with a 3D-printed prototype, he took the design through 100 iterations, tweaking it so it would securely hold the line in place but also allow for the line’s fast and easy removal.
