Nearly 700 guns, several hand grenades and a pocket knife in a medicine bottle. Those are just some of the things the TSA has confiscated in the first two months of the year at airport security checkpoints.

At least 687 firearms were caught by agents through March 3 of this year, according to a TSA blog. That's 11.1 per day. Of those, 490 were loaded and 216 -- 3.5 per day -- had a round chambered.

The TSA says handguns must be unloaded and kept in checked baggage in a hard-sided container. The same thing goes for ammunition, magazines, clips and other firearms parts, but it seems people still don't get the message or ignore it. The 11.1 firearms each day is almost on pace with last year's record of 11.6 per day (4,239 firearms for the year).

Some things you may consider to be safe for your carry-on may not be. The TSA confiscated a seat belt cutter -- also in Columbus -- that contains a small knife. That also needs to be in checked baggage.
