|Function||Melee combat, climbing and digging|
|User(s)||Toa Hordika Nokama (formerly)|
|Status||Transformed back into Hydro Blades|
The Fin Barbs were the Toa Tools that Nokama used during her time as a Toa Hordika. They were used for climbing and digging through most substances (in the movie, they were used like a combination bola and grappling hook), and could charge her Rhotuka water spinner.
Nokama lost the Fin Barbs when she was transformed back into a Toa Metru.
The blades of the Fin Barbs were comprised of rubbery plastic, the handles and blue parts were normal, hard plastic.
- A large foam version of this weapon was released in 2005.
