Skulls and Shackles
The blade of this cutlass is spotted with rust.
The blade of this +1 cutlass (Pirates of the Inner Sea 18) is spotted with rust, and its basket hilt is cast in the likeness of a grinning skull. Once per day, a tidewater cutlass can be used to cast hydraulic push.
Tidewater cutlasses are not uncommon weapons among the pirates of the Shackles, at least for those who can afford to buy one or who manage to loot one from someone who can.
