Are you looking for a good padlock or lock cylinder?

If you are looking for a lock that is difficult to pick, you should look for locks that are difficult for amateur lock pickers to pick ๐Ÿ˜. When lockpicking, different colored belts can be achieved, ranging from white (easiest) to black (hardest).
