Diagram: Viper venomous steel sword is a diagram in the Hearts of Stone expansion.

During the main quest Open Sesame!, after getting into the vault, no matter your choices, this will be in a chest near the table Maximilian Borsodi's house was on. This is the only time you can get it without mods, so make sure to grab it when you have the chance.
