I need help to critically analyze the poem "Out, Out—" by Robert Frost

I suggest beginning with the origins of the title as
Macbeth's lament after the suicide of his wife Lady Macbeth (from the play by
Shakespeare). There is with both deaths an inconvenience suggested. Macbeth is in the
midst of fighting to retain the crown, and the woodsman have a job to finish. Both
deaths seem to be more of a momentary diversion than a greatly mourned
loss.

The poem makes great use of sibilance (repetition of
the 's' sound) to emphasise the menacing action of the saw, and the boy's life ebbing
away.

The buzz
saw snarled and rattled

Frost
also makes use of the caesura (an unnatural pause within a line) to suggest the
interruption and halting of the day's work - and the life of the
boy.

So. But
the hand was gone already

The
saw is also personified to suggest it is as responsible for the accident as the boy's
carelessness or his distractor's voice. It gives the saw a cruel appearance
too.
