"O engenheiro compra uma ferramenta."

Translation: The engineer buys a tool.

[mariaaa]

Is "ferramenta" used only in connection with manual tools like hammers, screwdrivers etc. or can it also refer to an electric tool such as a drill, electric saw etc?

[Paulenrique]

In many senses... anything you use to perform a task... it also may include books, clinical instruments, etc.

[ThanKwee]

Ah, so it can also mean "tools of the trade"
