I just introduced a very practical multi-functional bottle opener a week ago, which can be used to open various bottle caps such as beer bottles, cans, soda cans, beverage bottles, etc. But it seems that the multi-functional bottle opener cannot be used to open wine corks. Then, with today's introduction of this bottle opener knife, there is probably no bottle cap that cannot be opened. With these two bottle openers in hand, there won't be a situation where you have wine but can't drink it. In addition to opening beer bottles and wine bottles, this bottle opener knife also has a small cutting knife, which is often needed, and it can also be carried with you as a keychain.
