looked it up in Wikipedia:

Atropos was the oldest of the Three Fates, and was known as the "inflexible" or "inevitable". It was Atropos who chose the mechanism of death and ended the life of each mortal by cutting their thread with her "abhorred shears". She worked along with her two sisters, Clotho, who spun the thread, and Lachesis, who measured the length.
