An improved manually operated torque magnifying impact tool is provided having an improved inertia member construction, separate cams for disengaging certain operating members, an improved tool head, improved mechanism for stopping the inertia member, mechanism to limit the decompressive movement of the power spring to absorb the shock associated with such movement, mechanism to utilize the power spring to stop the inertia member resiliently to reduce stress on tool parts, mechanism to accomplish a more uniform input force requirement on the tool head axis, and mechanism to reduce the force of the pawls against the ratchet teeth at the moment of disengagement.
