pocketknifes are useful tools for getting out of sticky situations. metaphorically, if you say “ooh i have a pocketknife” you mean that you have just thought of a way to get out of a sticky situation. it could also mean that you literally have a pocketknife on hand
example one:
person 1: i don’t want to go to the party because my ex will be there and we planned on going together
person 2: ooh i have a pocketknife! you could come with me to my sister’s preschool graduation!
