Pocket clips are a great thing to have. They float your keys toward the top of your pocket rather than allowing them to clump together at the bottom in an annoying bulge. It's convenient and easy. But most of them do not have other functions. Not the TT-Capper, though. This tiny American-made titanium clip is also a multi-tool. It functions as a bottle opener, pry bar, and flathead driver on top of being a pocket or hat clip.
