"A survival knife for enthusiasts. It still looks useable."
The Survival Knife (サバイバルナイフ sabaibarunaifu ) is a weapon that appears in Resident Evil 7: Biohazard.
The Survival Knife is made available as Mia's melee weapon in the Sea Transport tape. After finishing the tape, the knife can be found on the 2nd floor of the carrier, in front of Mia after climbing out of the elevator. On Madhouse difficulty, the Survival Knife is moved from its original position to being stuck in a table inside the Recreation Room on the first floor (Wrecked Ship 1F). In this location, a Corrosive is required to open the door to the Rec Room and retrieve the knife.
After rescuing Ethan, the survival knife along with what were in Mia's inventory are automatically transferred to the Item Box for Ethan's use. Compared to Ethan's folding knife, it has high damage output, being able to kill a Regular Molded in 4 hits to the head and 6 hits to the head of a Spiked Armed Molded. It also has slightly longer range.
In Ethan Must Die mode, the survival knife can easily clear hives and take down normal molded (albeit still highly risky).
