Borderlands 4 players have discovered a truly game-breaking Throwing Knife that can kill bosses and enemies within seconds, stacking damage within the billions by re-applying the Throwing Knife. Since Gearbox is unlikely to nerf this Throwing Knife ASAP, players are going to want to find the best Throwing Knife farm in Borderlands 4 if they want to join the cool kids club and absolutely eradicate bosses. Below, we’ve listed the most effective place to get the Throwing Knife, and the exact Throwing Knife that they’re seeking out.

How to Farm the Best Throwing Knife in Borderlands 4

The best Throwing Knife in Borderlands 4 is random loot, meaning there is no dedicated loot pool that can be used to farm it. However, there is a specific boss that players are reporting as more successful than others, specifically due to how fast the boss can be killed, and the loot that’s obtained from the Red Chest in the reward room. In order to farm the best Throwing Knife, players must kill Driller Hole, the boss located at Queen’s Cradle in Tonnage Peel, Carcadia Burn, available after the “Unpaid Tab” Main Mission. Driller Hole has an Armor bar and then a Flesh bar, so bring Corrosive/Cryo and Incendiary to wipe him out fast. Driller Hole drops a mighty amount of loot, but he mainly drops Ordnance like Throwing Knives. However, once defeated, the southeast door will open and reveal a Red Chest, which has a larger chance of spawning the Throwing Knife that you seek. Players are going to want to keep farming Driller Hole to open the Red Chest repeatedly until their knife drops.
