In addition to a knife and a Leatherman or SOG multitool, I carry a separate pair of Channellock 4.5 inch tongue and groove pliers, model 424: http://www.channellock.com/acb/stores/1/4_5_inch_Tongue_and_Groove_Pli_P112C3.cfm Weighing only 1.6 ounces, the USA-made Channellock pliers are lightweight and small enough to be carried easily in my pants pocket. The blue plastic cushions are comfortable. The additional pliers comes in handy in a variety of situations, including turning a bolt with the multitool pliers while holding the associated nut with the Channellock pliers. The Channellock's jaws remain parallel to each other in most situations and don't slip off of the object they are grasping. I bought the Channellock pliers at Farm & Fleet, but have not seen them sold at many other stores.
