COLD STEEL RECON 1 MICRO SPEAR POINT
Have used various knives attached to my work van keys over the years. This is the best so far. It's a proper knife that can be used for every day tasks. The handle shape may look a bit strange , but in hand , especially with keys (or lanyard) attached the ergonomics are very good. Have used mine for a couple of years. Bought another recently for my son.
