The Survival Knife (サバイバルナイフ, Sabaibaru Naifu?), also known as Lightning's Knife, or Keepsake Knife (お守りのナイフ, Omamori no Naifu?, lit. Good-Luck Charm Knife) in Final Fantasy Record Keeper, is an important item in the Final Fantasy XIII trilogy. It is an ornate present that Lightning received on her twenty-first birthday from her sister Serah. "OP148" is engraved on the disc in the Cocoon alphabet.
Serah purchased the Survival Knife as a gift for her sister Lightning's twenty-first birthday. At Lightning's birthday dinner, Serah revealed that she had become a l'Cie, as well as that she intends to marry her boyfriend, Snow Villiers. These words greatly upset Lightning, who refused to believe her. After Serah left the house with Snow in pursuit, Lightning opened the gift box and discovered the Survival Knife. As she beheld Serah's gift Lightning realized her sister had been telling the truth, but it was too late to make amends.
In Palumpolum, Hope is placed under Snow's care though he despises the man. After the two defeat the Ushumgal Subjugator, a powerful PSICOM military unit, Hope confronts Snow about the death of his mother and attempts to kill him with the Survival Knife. Before he can do this, a PSICOM missile hits the building, throwing Hope off the edge of the rooftop they were standing on. Snow catches the boy in midair and uses his body to shield him from the fall. When Hope comes to, Snow returns the Survival Knife to him and divulges the story behind it and the two make amends. The Ushumgal Subjugator returns and knocks out the wounded Snow. Hope defends him alone until Lightning and Oerba Yun Fang come to his aid, and after the Ushumgal Subjugator is destroyed, Hope returns the Survival Knife to Lightning.
Lightning disappeared on the Day of Ragnarok and Hope discovered the Survival Knife under the base of Cocoon's crystal pillar. He handed it to Serah, who keeps it in her room in New Bodhum. When Noel Kreiss arrives two years after Lightning's disappearance, he asks Serah to aid him in his search for an artefact used to open the Time Gate that crashed on the town's outskirts. It is called Lightning's Knife in the inventory.
During their search for the artefact, Serah and Noel come across the Survival Knife, which, to Serah's surprise, has been polished. The two believe this to be the result of a paradox, but in actuality, the Survival Knife had been polished by Gadot, who claims Lightning would be mad if she learned the Survival Knife was "poorly maintained."

- Serah gifting a knife to Lightning as her birthday present might be foreshadowing; according to superstition, gifting a knife is bad luck, and symbolizes cutting relations with that person.
