A firefighter pocket tool achieves its objectives by combining the functional features of several traditional tools (slip groove pliers of the curved jaw type, 6 in 1 screwdriver, spanner wrench, gas shut off tool and a striking tool) onto a shared single structure. The structure of the firefighter pocket tool comprises a pair of slip groove plier members each having a jaw portion, a joint portion and a handle portion, a pivotal bolt, nut and spring member. The upper jaw of the slip groove pliers is of the curved jaw type. Upon the “upper” rear portion of the pliers' “upper” jaw's head there is formed a protrusion that forms a striking surface and a hook and claw. The hook and claw is located so as to allow it to be used as a spanner for rocker lug type and similar fire hose couplings. As this same plier member crosses over the other plier member, it forms a plurality of arcuate adjustable channels with which the arcuate protuberance from the other plier member is engaged. Protruding from the top or rear handle (just above the gripping area) is another protrusion. This protrusion is of a rectangular shape. In the middle of this protrusion is a loop in the shape slightly larger than standard natural gas shut off valves. Two independently sized hexagonal open shafts that form the handles and nut-driver / bit holders. The spanner hook and claw could also be used to operate valves (such as smaller gas supply shut offs). The gas shut off loop can also be used as a guard for fingers when the tool is being used as a striking implement.
