Abstract: A cylinder wrench for inserting and removing cylinder valves from pressurized cylinders, and a vise assembly for firmly gripping cumbersome objects such as pressurized cylinders and large diameter pipes. The long-handled vise assembly includes a chain which is wrapped about the pipe for cylinder and then tightened to provide a firm grip. The wrench assembly mates with the cylinder valve and includes a gripping bar that permits high torque to be applied to the valve. Counteracting torque can be applied to the cylinder by gripping it with the vise assembly and bracing the vise assembly handle.
