I'm just a touch late to this thread, but I've always been a big fan of spyderco folders. I have the old version of the plain edge endura and rescue with the plastic pocket clip and I still carry them quite a lot. The endura has held up to a lot of abuse over the years, and it's served me well. The rescue is more of a specialty deal, but I like it a lot for rope and webbing tasks - the serrations go through nylon webbing like butter. Nice knife to carry rock climbing for cleaning old rotting webbing off anchors and rappel stations.
