The things I bite, they don't bleed, I don't bite until you push me; I bring my victims together each time I bite, But they'll come undone if you pull it just right. What am I?

Why this works

This riddle cleverly uses the metaphor of "biting" to describe how a stapler functions. When you push down on a stapler, it "bites" through sheets of paper to bind them together, but, unlike an animal bite, it doesn't cause bleeding. The phrase "bring my victims together" refers to how a stapler holds multiple pieces of paper together, while "come undone if you pull it just right" alludes to how you can remove a staple by using a staple puller or by pulling it out directly. This playful language creates a vivid image of the stapler's action in a way that transforms an ordinary office tool into a character in a riddle!
