Here's another new one for Transportation Security Administration (TSA) screeners at Miami International Airport.

In the last week, screeners found seven undeclared firearms concealed in a checked toolbox.

Take a close look at the above picture courtesy of TSA.

The TSA folks have yet to say which flight this toolbox gun set was on and if the traveler was arrested.

They say it is legal to travel with firearms and ammunition in checked baggage as long as proper guidelines are followed.

Each state and airline has their own rules.

TSA suggests checking with your airline to see what their procedure is.
