The stelar cylindrical padlock is more resistant to brute force attacks compared to ordinary locks because the thickness of the cylindrical body is greater than that of normal rectangular padlocks. This allows one to insert, with the same body width, internal components and shackles which are larger in size. The shackle, in particular, is one of the critical factors for the security of a padlock, because it is the component most exposed to attacks. The shackle can reach a diameter of 14 mm in stelar cylindrical padlocks, whilst in the normal rectangular padlocks it typically does not exceed 12 mm. An extra two millimetres in diameter corresponds to a 36% larger section, which is much more difficult to break or cut.
