In a second preferred embodiment for providing an anesthetic gel to the upper surface of the blade, the blade includes a fluid conduit manifold for providing fluid communication between the reservoir and the upper surface of the blade. In an alternative preferred embodiment for providing an anesthetic gel to the tipper surface of the blade, the blade includes a porous layer located on the upper surface of the blade, the porous layer being adapted to contain an anesthetic gel.
