Caesar's Hero Knife

A substance, designed to help the brain repair itself, gives rise to a super-intelligent chimp who leads an ape uprising. This is Caesar's hero knife used in the 2011 film, Rise of the Planet of the Apes. This exact knife can be seen when Caesar steals it from one of Dodge's friends that is brought into the cage area, affixes it to a stick found in the yard and makes a tool to unlock his cage. It can also be seen later after going back to Will's house in the middle of the night. Caesar steals two canisters of the ALZ 113 drug and uses the knife to puncture the canisters to release the drug to the rest of the monkeys in the sanctuary. This knife still has traces of "hair" from the device used on set to act as Caesar when the knife was being used during filming.
