In the heart of the door, I gleam with might, like a leprechaun's gold in the dark o' night. Turn me once, and luck shall sprout, unlockin' secrets with a merry shout!

I am round and often turned by hand. I help you open or close a door. What am I?

Though I am thinner than a thread, between your teeth I often tread. I help remove what should not stay, what am I that’s used each day?

Every year children attack me with blades, disembowel me, then leave me on their porch. Sometimes they even use my skull as a candy dish!

This little doo-dad It's quite convenient Until you need the name of it. It's so helpful they named A gremlin after it!
