mechanical puzzle Luban Lock

📌 Where it came from

It is associated with Luban (Lu Ban) — a legendary Chinese carpenter, engineer, and inventor who lived around the 5th century BCE.

According to tradition, he invented methods of joining wooden parts without nails or glue.

In short, the toy has Chinese origins and is part of a centuries-old tradition of woodworking puzzles.
