Universal key for simple locks

The key is mounted on a small engine with an eccentric, the rotation of which creates an oscillation that reveals the secret of the lock. The key body is made of a hacksaw blade, it is a strong but brittle material that, with great effort, can break and remain inside the keyhole. The electric key will be able to cope with simple padlocks made in China, if they did not have time to turn sour or rust, then the native key will cope with difficulty.

This craft should be used very carefully, remember that this is a real spy tool.
