An improved immersion blender generally consisting of a motor, an elongated motor shaft that extends from the motor through a removable tubular guard to a back-to-back radial-flow cutter blade. The cutter blade is securely attached to the distal end of motor shaft and is housed within the tubular guard assembly. The tubular guard has a manifold at its distal end that provides side inlet and outlet ports for the blade and a lower inlet aperture through the distal annular plate of the manifold. The lower blade of the back-to-back radial-flow cutter draws liquid from the bottom portion of the container, through the lower inlet side-ports in the manifold and the aperture through the distal end of the manifold, and discharges the liquid through the outlet ports in the manifold toward the sides of container in a radial direction. The upper blade draws the liquid from the top portion of the container, through the upper inlet side-ports in the manifold, and discharges the liquid through the outlet ports toward the sides of container in a radial direction. The flow of the liquid drawn into the blades is towards the center axis of the motor shaft, and the flow of the liquid discharged from the blades is away from the center axis of the motor shaft.
