The Razor's Edge is a novel by W. Somerset Maugham written in 1944. Its epigraph reads, "The sharp edge of a razor is difficult to pass over; thus the wise say the path to Salvation is hard." —Katha-Upanishad.

The Razor's Edge tells the story of an American, Larry Darrell, who, traumatized by his experiences as a fighter pilot in World War I, decides to search for some transcendant meaning in his life. The novel tells its story through the eyes of Larry's friends and acquaintances as they witness his personality change after the War. His rejection of conventional life and search for meaningful experience allows him to thrive while the more materialistic characters suffer reversals of fortune. The book was twice adapted into film, first in 1946 starring Tyrone Power and Gene Tierney and a modern adaptation 1984 version starring Bill Murray in the lead, with Tibet replacing India as the place of Larry's enlightenment.
