How does a wine opener differ from corkscrew?

The terms are often used interchangeably, but there are some nuances:

* Corkscrew is the general term for any tool used to remove corks. This includes basic single-pronged versions, waiter's friends, and electric openers.

* Wine opener is a broader term that encompasses all tools used to open wine bottles, including not just corkscrews, but also wine keys (for twist-off caps) and bottle stoppers.

So, while every wine opener is a corkscrew, not every corkscrew is a wine opener.

Here's a way to think about it:

* Corkscrew is the tool, like a hammer.

* Wine opener is the action of opening a wine bottle, like hammering a nail.

In short, a corkscrew is a specific type of wine opener.
