My go-to gentleman's knife is my Mnandi. Small, no flipper or thumbstud (but can still be opened one handed), and very nice fit and finish. I feel comfortable using it around most people and confident it'll perform the cutting task I use it for. If I'm concerned about carrying an expensive knife I'll bring my Boker FR instead. Not quite as stylish and has a flipper tab, but still slender and capable. On the bigger side, I love my Boker Exskelibur with carbon fiber handle. Something about a nice front flipper is elegant to me and I do love the way it rides in the pocket. Probably one of the slimmest knives I own and close to one of the best slicers. Was riding in a limo with a few other gentleman where one of them was trying to slice up a lemon for our drinks with some kind of small traditional. It was actually a pretty nice looking knife, but wasn't doing much to slice the lemon. I pulled out my Exskelibur, sliced up the lemon, wiped off the blade, put the knife back in my pocket, and continued my conversation. The gentleman with the traditional knife gave me a quizzical look for a second then joined back into the conversation. Would've liked to get a better look at his traditional and show him my knife, but alas, little time for knife talk on that occasion.
