* The bow and arrow: This is her signature weapon and the one she's most associated with. It's her primary hunting tool and the weapon she uses to win the Games. She's incredibly skilled with it and can hit targets from great distances.
* The knife: This is her secondary weapon and the one she uses for close combat. She's also very proficient with it and is able to use it to kill and defend herself.
* The sword: While not as prominently featured, Katniss demonstrates her skill with the sword in several instances, particularly when she's forced to use it in close combat scenarios in the arena.
Ultimately, the "best" weapon for Katniss depends on the situation. Her bow and arrow is ideal for long-range attacks and hunting, while her knife and sword are crucial for close-quarters combat.
It's important to note that Katniss's success isn't just due to her weaponry, but also her resourcefulness, cunning, and ability to adapt to different situations. She's a skilled survivalist and a fierce competitor, and she's willing to use any tool at her disposal to survive.
