It’s a combination of a bottle opener, a hex fin key, a flat head fin key, and a wax comb and stripper. So you can adjust your surfboard, crack open a beer, and more with just one gadget. Measuring only 105 mm by 25 mm by 13 mm and weighing only 49 grams, it’s portable and lightweight to take everywhere. Moreover, the Windeler Surf Stak is 100 percent non-corrosive, easy to clean, and impervious to saltwater and salt.
