The BO-4 is an amazing combination of a corkscrew and a bottle opener, along with a handy knife and foil cutter. Crafted in the tradition of Park Tool's top - notch fold - up bike tools, it's designed for easy storage as it folds neatly. The tool features all stainless - steel mechanisms housed in a strong forged aluminum case. This high - quality beverage tool is perfect for your workbench, toolbox, or a cozy wine bar. It has a corkscrew, bottle opener, and foil knife, ensuring you're well - equipped for any beverage - opening task.


Using the BO - 4 is a breeze. To open a bottle, simply use the bottle opener part to pop off the cap. For wine bottles, first use the foil knife to cut through the foil on the top of the bottle. Then, insert the corkscrew into the cork and turn it gently until the cork is out. When not in use, fold it up for easy storage. As for maintenance, keep it clean by wiping it with a dry cloth after each use. Avoid exposing it to extreme moisture or corrosive substances. If it gets dirty, you can wash it with mild soap and water, then dry it thoroughly.
