Like all the other unlockables, the Circular Saw will be put in the Item Box on subsequent playthroughs and refreshes in the Item Box should players discard it at any given time. The Circular Saw has a considerable amount of power compared to other melee weapons such as the Knife, being able to severely damage enemies and stop their assault.
The weapon has two types of attack with one being a slash and the other is making the saw continuosly run, being able to eradicate enemies within seconds. The former only requires the player to press the attack button while the latter requires the player to hold the ready weapon button and hold the attack button.
Dubbed the "Melle Rocket Launcher" by classic RE fans.
