The Legend of Zelda: Tears of the Kingdom tends to use everyday objects like a Boat Oar as makeshift weapons until you find a better and proper alternative.
While it looks sturdy enough to be used against strong currents, you are going to be wielding the Boat Oar as a two-handed wooden weapon to defend yourself against enemies.
Featuring a base attack of 4, here is how you can find the Boat Oar in Zelda: TotK.
