Airports in the US are still reporting large numbers of banned items being seized from passengers who are seemingly unaware of the regulations. For example, Federal screeners at Logan International Airport are still seizing roughly

11,500 banned items, such as knives, scissors, and pepper spray from passengers every month.
The ban on cigarette lighters in hand luggage on planes has also resulted in the confiscation of roughly 14,000 lighters a month. Transportation Security Administration (TSA) officials have now begun to make ''amnesty bins’ available at this and other airports for passengers to drop banned items prior to security search and to avoid heavy fines for carrying the items.
