> In Japan if you are found with lock picks you will be subject to a fine of 500,000 yen and a year in prison. In Poland, it is illegal to possess any picks without being able to show that your profession requires it ... In Hungary ownership of lock picks is completely illegal. The only people in Hungary that are allowed to have these tools are the military, and as a result lock picks are classified as military equipment. For travel within the United States or even traveling to the US, you should consult the lock pick laws in the state you are visiting.
