The idiomatic meaning of "a swiss army knife" refers to something that is highly versatile, adaptable, and possesses a wide range of functions or uses. It describes something that can be used for many different purposes, like the physical tool itself.
The expression is derived directly from the actual Swiss Army knife, a multi-tool pocketknife famously manufactured in Switzerland. Its compact design incorporates various tools like blades, screwdrivers, bottle openers, and more, making it a practical and versatile item.
The register is generally neutral, suitable for both informal and formal contexts, although overuse can sound slightly cliché.
The expression "a swiss army knife" is typically used as a simile, often preceded by "like" or "as". It can be modified with adjectives to further specify the type of versatility being described (e.g., "a digital Swiss Army knife"). It can be used in questions and negative statements.
What sounds unnatural is using it too literally or in a context where the versatility is not a positive attribute. It also sounds odd to over-modify it with excessive adjectives or adverbs. For example, saying "a very Swiss Army knife-like thing" is redundant and awkward.

While the phrase originates from a literal object, it's almost always used figuratively to describe something with many functions or capabilities. You might hear someone say "I have a Swiss Army knife in my bag" literally, but the idiomatic usage is far more common, describing a person, tool, or system's versatility.
Both phrases describe versatility, but "a swiss army knife" focuses on the range of functions, implying competence across many tasks. "A jack-of-all-trades" can also imply mastery of none, or a superficial level of skill in many areas, which is not necessarily the case with the "swiss army knife" metaphor.
The key to using the idiom correctly is to focus on the figurative meaning: versatility and multiple capabilities. If you're not emphasizing that something has a wide range of uses or functions, then you're likely using the phrase too literally and should choose a different expression.
