A single tool to open every type of bottle.
There are 3 GIFs that explain how to use it! For small bottles, use the loop; just slide it over the narrow part, and once you reach the bottom, just pull. For large bottles, use it like a regular bottle opener. For medium-sized bottles, use it the same way as the large ones, but you need to flip the tool upside down and lever against the bottle's thread. SIMPLE!
Let me know what you think!
The use of very rigid filaments is preferable; often, bottles are difficult to open, and a filament that bends may render the tool unusable
