As already mentioned it all depends on the agent when going through the securty check. We travelled in January and I had no problem going through with with a few needles and a medallion like cutter by Bohn.
Ironically, once inside the gate area after security, we did notice that the restaurant gave us real silverware - knives , forks and spoons to use to eat our lunch - and the server did not appear to be concerned about being sure that they were all still on the table when we left.
