[Minecraft] Where do Wither Skeletons get stone to make stone swords when they live in the Nether?

Lol i'm sure there's no answer but it's worth asking y'know?

There’s stone everywhere in the Nether, it’s just so hot that it’s been melted down into the lava you see. Now, you of course can’t use water to turn that lava back into cobblestone yourself in the Nether, but that doesn’t mean creatures native to the Nether don’t have some tricks up their sleeves. Hitting you with the sword infects you with the wither, which is evidence that there’s some connection between whatever magic keeps them going and gives them purpose and their weapons. So the most likely explanation is that they use their wither magic to harden the lava back into stone for their weapons, then they continue to channel that magic through the weapon until they’re destroyed causing the sword to revert back into a regular old stone one.
