Top Designs of and Materials for Padlock Shackles

In a padlock, the shackle is the U-shaped metallic rod that loops through a locker staple, a chain link, a latch lock and so on. Its exposed shape makes it easy to cut with a saw or bolt cutter, pick with a claw bar or hammer or even grinding. There are different designs and lengths of shackles, each providing a different level of security. Shorter and concealed shackles would obviously be harder to access, but the locker design will determine whether the short manacle will slip through.
