Answer: At the time of the 9/11 incident, certain type utility or pocket knives like the ones the terrorists brought on board were not illegal. Airport screeners had more leeway then about what type of knives, tools, or other gadgets they allowed passengers to carry on board. Since then, the restrictions are far more stringent.
