As symbolically Steinbeck may be associating the knife with manhood.

It might also be important that Pepé likes carrying his father’s knife.
It is only when he leaves the farm to get medicine that life changes dramatically for Pepé and he makes the transition from boyhood to manhood. Pepé has some responsibilities but there is nothing for him to do that is too taxing or difficult. Pepé while he is on Mama Torres’ farm is living a life that many would associate with that of a nineteen year old boy.

Taken from his The Long Valley collection the story is narrated in the third person by an unnamed narrator and after reading the story the reader realises that Steinbeck maybe exploring the transition from innocence to manhood. In Flight by John Steinbeck we have the theme of innocence, coming of age, resilience, hardship, struggle, escape and loss.
