tooth and nail

With savage determination

Tooth and nail describes fighting or struggling with maximum ferocity, using every available weapon—as animals use both teeth and claws.

The phrase almost always follows verbs of conflict: They fought tooth and nail for custody, She defended her position tooth and nail.

It suggests desperate, all-out effort rather than measured resistance.
