A method of forming a lubricating coating on a razor blade that includes: providing a razor blade having a body and a cutting edge tapering from the body; providing a tank of a colloidal dispersion of a polymer having less than 2% in weight of polymer particles; providing a spray gun in fluid communication with the tank, the gun having an end directed to a blade-spraying region; placing the razor blade at a predetermined temperature (T) in the blade-spraying region; flowing the colloidal dispersion from the tank to the end of the spray gun, and in a direction to the razor blade; controlling a first gas stream to nebulise the colloidal dispersion into a mist in a dispersion region located between the end of the spray gun and the razor blade; independently controlling a second gas stream to control the mist properties; transporting the mist from the dispersion region to the razor blade placed in the blade-spraying region, the razor blade being at the predetermined temperature (T) so that water evaporates from the mist, and sintering the polymer.
