Margaret Devaney’s Pocketknife

Origins
Margaret boarded RMS Titanic as a third-class passenger with her friends Mary Burns and Catherine "Kate" Hargadon at Queenstown, Ireland. When the Titanic hit an iceberg on the night of April 14, 1912, Margaret, Mary and Catherine climbed a ladder from the Aft Well deck to a deck of the second-class. One of Margaret's friends suffered from seasickness and stopped, along with the other friend. Margaret intended to come back for them when she found a lifeboat. However, once in the crowd, she found herself near Collapsible C and was pushed in. While Collapsible C was being lowered, it got caught on the Titanic's rivets. The crew had trouble loosening the falls to free the lifeboat. Margaret took a pocketknife and gave it to the crewman. The crewman managed to free Collapsible C. Mary and Catherine perished. Their bodies, if recovered, were never identified.

Effects
The blade is super sharp, hardened from the circumstances of that cold night. It can cut through anything with little pressure, whether rope, steel, flesh, bark, concrete and even diamond. It seems to work better at cold temperatures than warmer ones.

Trivia
Many agents believe that the two other objects she took from the sinking had become artifacts as well. Her third class ticket was stolen and replaced with a fake at an exhibition, while the emblem flag taken off of her lifeboat still remains in the family’s possession. They are thought to have either coldness or logic inducing effects due to her quick thinking on that fateful night.
