(KRON/CNN) — A record-breaking week for firearms found in carry-on bags at airports around the nation.

The TSA said from Aug. 5 to Aug. 11, they discovered 78 guns. Of those, 68 were loaded and 21 had a round in the chamber.

The previous high-water mark for firearms found in a week was 74. That was in May of this year.

The TSA maintains in many cases that travelers simply forgot they had weapons with them.

And it is not just firearms.

TSA agents found a knife inside a pill bottle in San Francisco.

And they said they found four replica grenades in the past week.
