Abstract
The disclosed invention uses an open-top vessel for supporting a water rinsed razor and its blade, the vessel being filled with mineral oil to a level above the blade. Different mechanisms are used for holding the razor and for moving the submerged razor and mineral oil relative to one another. One mechanism comprises mechanically gripping the razor and moving it through the mineral oil contained within the vessel. Another mechanism comprises moving the mineral oil, by pumping it or vibrating it, relative the razor. The disclosed invention also uses a portable storage vessel having a brush bristle outlet for the mineral oil, and brushing the mineral oil onto the blade manually. In using all such mechanisms, the razor blade is effectively coated with the mineral oil to isolate it from the atmospheric air and thereby protect it from dulling caused by corrosion.
