I like and use the Park MTB3; it has very high quality hardened steel tools which still have no signs of wear. BUT I also carry a Leatherman like folding miniature pliers by Eddie Baur (sp?) from Target for $12. AND I carry tire irons because the levers on the MTB3 are too wide for road tires (but I use this tool on my mtb anyways); along those lines I also carry the Quik Stik that enables very rapid removal of the tire bead.
