So well deigned, it's even used by the military. The Leatherman MUT Tactical Multi-Tool packs 16 different utensils including regular and needle-nose pliers, wire cutters, a hammer, saw and a range of screwdrivers. Forged from stainless steel, bronze carbon and titanium, it comes with a MOLLE sheath and is easily operable with just the one hand. That's if you can multi-task.
