One of a Kind

Hi Group,

I heard a sentence like "He's one of a kind" what does it mean in the first place and I heard this phase from an object too"Take it easy, is one of a kind" what does it mean this context too? Can you give me some examples to understand better the context and the meaning.

If I am missing an example, please let me know.

Thanks in advance,
Antonio.

There's something unique or different about him. He's unlike the rest of the pack.
