If it is formal wear or a funeral suit, I carry something with at least a black pocket clip, usually an all black knife. A PM 2, though I thought about getting the Emerson A100, as pictured before, for just such occasions. I understand why a pocketed slip-joint would be potentially preferable to people, but I do not carry one usually, and am generally comfortable carrying any of the folding knives I own. That being said, I recently purchased a Winkler F3 folder with curly maple handles to serve as a gentleman's knife for me. My thought was, and I think it was mentioned earlier, that you can't go wrong with wood.
