a vintage take-apart trick puzzle keychain (often called a "sweetheart" puzzle).How it WorksThe Secret Lock: The heart acts as a hidden mechanism holding the crescent-shaped ring secure. The Trick: To slide keys onto the loop, you must press down, slide, or tilt the rectangular center panel on the heart. This action releases the tension on the metal bar so it can swing clear, revealing the hidden opening in the loop.The Bottom Stamp: At the very bottom tip, it features a small stamp reading "PAT. PEND." (Patent Pending), which is typical of mid-20th-century novelty hardware.
