A jarring tool for use in a drill string to prevent sticking of the drill string during drilling operations. The jarring tool has a torque assembly for continually torquing the jar and thus the drilling operation need not be discontinued upon encountering an interfering object. The jarring tool is particularly suited for high viscosity drilling operations and eliminates hydrostatic sticking of the drill string by providing an immediate jarring action utilizing a simple hammer and anvil construction. The jarring tool is also suitable for use in a "fishing" string.
