Found a tiny screwdriver set in the junk drawer, and it's perfect for fixing the wobbly keychain that's been threatening to drop my house keys. Tweaking those minuscule screws on the key ring takes a steady hand and the right tool. A few gentle turns, and the key loop is snug again, no more jangling loose parts or worrying about losing the spare mailbox key. It's satisfying to restore something small back to proper working order without needing a trip to the hardware store.
