I know sea prism stones are extremely hard and can't remember any moment where
I have seen anyone to cut or break them. If someone is cuffed with them and he
or she happens to be extremely powerful and not a devil fruit eater can he or
she break it? Can a swordsman cut it?

Can Sea Prism Stones be cut or broken?


So far in the series, we have not had any instances where seastone was
directly broken apart, whether with brute force or with a weapon like a sword.
In cases where characters like Robin or Ace were restrained with seastone
handcuffs, they were unlocked using the keys. Whether it **can** be done
remains an open question, as we have seen both Zoro and Mihawk cut through
other extremely solid objects in the past.

However, the mineral itself is not indestructible even though it is said to be
as hard as a diamond. This is evident because the Marines are able to shape it
into a variety of items like handcuffs, prison bars, weapons (like Smoker's
sword) and even use it to coat the bottom of ships to escape Sea Kings. You
can find the other limitations we know about seastone in the
[wikia](https://onepiece.fandom.com/wiki/Seastone).

In the latest manga chapters, we come to know that seastone may have
originated

> in Wano, and that there exist craftsmen with expertise in working with the
> mineral.
