When I wear a suit I wear a Citizen Eco Drive square face and carry a mini Victorinox so I am never without a knife. Most courthouses will let it slide and if they don't I am not out much when I need to toss one because a bought 25 of them for .50 each about 15 years ago from E-bay that had been TSA confiscated. Causal wear I have a Timex Indiglo and carry the mini Victorinox and a Microtech Ultratech or a Gerber pocket clip Multitool.
