In fact, in order to unlock the postman puzzle, one had to solve a puzzle that was designed in a spiral. Although it seems that such a lock has a lot of functionality, opening the Security door that was equipped with this lock was not so difficult and complicated.

The only good thing about these postman locks was that they save a lot of time for thieves. In the meantime, their main disadvantage was that the owner of the house had to spend a lot of time on this lock to leave his house. That's why they went out of the way very soon and didn't get much popularity.

In such a situation, it is enough for the thief to put a little pressure on the part of the lock tab so that it is separated from the shackle and opened.
