"Lather well and you will shave well"
Looking at the machine, I can figure out how it works generally though the mechanism details I'm not certain of. It appears to have a Valet self strop razor blade in place and I'm not sure if the machine will work on any razor blade or if it requires specific design blades. Last thing I wonder is how many razor blades could you buy for the price of this unit?
