It is also illegal in Texas to have one in your car. As mentioned, the Texas Concealed Handgun license only applies to a HANDGUN, not a baton, sap, club, illegal knife, sword,..... check the Texas Penal code chapter 46 for weapons regulations.
If you are in another state, I don't have a clue as to what is legal there
