Lock smithery is one of the oldest crafts of human. Evidence suggests that Iranians have long been familiar with this craft, playing an important role in the development of it.
The traditional Iranian locks are among the most diverse and artistic locks in the world, which do not just have security implications, but are inspired by the beliefs of the people. For example, when an accident occurred and people were horrified, they threw out certain locks into the water, believing that if they drank it, they would be safe from the dangers!
The primary material for lock smithery is raw steel, which is selected for its strength and its hammering properties. To create a lock, the lock smith must first design the lock and special mechanics in its mind, then cut the metal plate and hammer it to the desired shape. Afterward, all the parts are paired together with the wire, using the brass strips to weld the parts that are attached together. Then the lock is placed in the furnace in order for the brass to melt and cover all the parts.
Then come the engraving and polishing the surface of the lock. The next step is to make the curve and latch and place it inside the lock. In the final step, a key is made for the lock. Common figures of these locks can be of animals, boats, hearts, and tubes. Producing each lock usually takes between two days to two months, depending on the complexity of its structure.
