Its length from the pointed tip of its handle to its very farthest part in the bumper is 5.75 inches, 6 inches, 15.25 inches of 15.5 inches depending on whether it is fully compacted or fully extended and whether the bumper axis is pointing in the direction of the handle or perpendicular to it. This fine extendable Rabiner Babinski percussor has been fitted with one of our never-age silicone bumpers. It will not get hard, it will not get gooey or liquefy, it will not deteriorate with time, it will not crack even when exposed to ozone the way rubber does. It is hard to find an extending Rabiner Babinski percussor that isn't an atrocious instrument, but Medworks insists on quality you can count on. Its nominal weight is 4.6 ounces but may vary from 4.5 to 4.7.
