TSA strikes again

I left Atlanta this morning to fly to Chicago for ISD. Last night as I was packing my bag and going through my laptop backpack to ensure that I didn't have any "contraband" that would raise the ire of a TSA agent. I had a Leatherman that I took out. Removed a USB drive that had a pen knife in it. Made sure not to pack my Cross Fountain Pen because there is no way in the world that I would throw it away if they told me I couldn't take it on the plane. I was careful to pack on liquids that were less than 3 ounces and packed them all in one 1 quart clear plastic bag.

As I went through security at the Atlanta airport all went well as my bags passed through the x-ray scanner and I walked through the metal detector. I grabbed my bag and other stuff and put it all back where it belongs and went on my merry way to the gate. The flight went well and I arrived in Chicago on time. As I was riding the train from the airport to the hotel all of a sudden I remembered that I had another knife in my laptop bag that I didn't remember taking out. It's a Buck 3" straight blade boot knife (don't ask why I carry it). I opened up the compartment that I keep it in and sure enough there it was. How the TSA missed it I'm not really sure. Now I'm faced with the delima of what to do with it. Do I take the chance that I can get it on the flight back to Atlanta? If they catch it what happens then? Do they just give me the option to give it up and go on my merry way or do the strip search me and put my name on the no fly list? Not real sure I'm willing to take that chance. Maybe I'll mail it to myself before I leave here.
