Resident Evil 4 Remake has several bonus weapons. We’ve already covered how to grab the hand cannon And How to unlock Infinite Rocket Launcherbut if you’re looking for a melee weapon to complement it, you’ll probably want to get your hands on the Primal Knife.
The Primal Knife is one of the most powerful melee weapons in Resident Evil 4 make new, and the only knife in the game that can be made unbreakable, so there are definitely plenty of reasons to hunt it down. Here’s how to unlock it.
How to unlock the Primal Knife in RE4 Remake
To unlock the Primal Knife RE4 Remake, you have to go collectible hunting. That means Destruction of 16 Clockwork Castellans, one per chapter of the game. Popping all 16 Clockwork Castellans will complete this Revolution Wind Up Challenge and unlock the Primordial Knife.
The only problem is that they are difficult to find. But no worry. We know where they all are.

Clockwork Castellan 9: Chapter 9 – Court Maze
This clockwork castellan is located in the upper left of the courtyard maze. Here’s an easy way to get there: After taking the steps down, skip the first exit on the left and take the second one. From there, turn left at each corner. You will eventually find the castellan behind a table.
Clockwork Castellan 10: Chapter 10 – Depths

Clockwork Castellan 11: Chapter 11: Layover
