Tonight I was dining at a nice restaurant (Rafferty's in Knoxville, TN) and i ordered the prime rib. While they bring a knife (if you can call the full serrated bad handled piece of steel a knife) with my steak I much rather preferred to use my own as it cut much better and the serrated one tears the meat more than it cuts it. As far as I know no one noticed me cutting my steak with my RSK and everything was fine. I also made a point of opening it slowly and using it like any other tool. If you open a knife with a fluorish and make it attention getting all you are doing is asking for trouble.
