Claim 19:
20. A drain cleaning device for removing debris from a drain pipe, the drain cleaning device comprising:
a handle section having an elongated upper handle defining a first axis and an elongated lower handle defining a second axis parallel to the first axis of rotation, the upper handle being adapted to rotate about the second axis to spin the drain cleaning device;
an elongated rod section operationally engaged with the handle section, the elongated rod section having at least three ribs, the three ribs being disposed along substantially an entire length of the elongated rod section, the three ribs following a curved path along the periphery of the elongated rod section, being configured to add structural rigidity to the elongated rod section, and being configured to facilitate the cleaning of grime from a side of a drain pipe;
a tip section connected to the elongated rod section, the tip section including a plurality of radial protrusions thereon adapted to be engaged with grime in a drain pipe by being rotated;
wherein the plurality of radial protrusions include a plurality of hook elements;
wherein the plurality of hook elements includes a plurality of injection-molded micro-hook elements;
wherein each micro-hook element has a thickness between approximately 0.25 millimeters and approximately 0.50 millimeters, and has a height between approximately 1.5 millimeters and approximately 2.0 millimeters;
wherein at least some of the plurality of injection-molded micro-hook elements are in the form of curved projections, J-shaped projections, T-shaped projections, or some combination thereof.
