Forum Support Mike J Posted June 22, 2017 Forum Support Posted June 22, 2017 Just a guess. Make the blades out of slightly softer steel than the steel mesh that covers the blades. As the blades move against the protective mesh while shaving, the flat surface of the blade would ever so slowly be honed away. This would keep them flat and with a nice square sharp edge. I expect it took a lot of trial and error to get the right combination of metals. I suppose you could also coat the underside of the protective mesh with something really hard, maybe some type of ceramic composite? 1 Link to comment Share on other sites More sharing options...

This sounds like how self sharpening chain saws are supposed to work but it never really worked in the past because the sharpening needs to be done on the underside of the cutting surface to keep the cutting surface from premature ejectulation. Recently, one of the chain saw makers got smart and made the top side of the teeth thicker so you could use the self-sharpening device without wearing out the chain so fast. Maybe self sharpening razors took that tip to the next level. 1 Link to comment Share on other sites More sharing options...
Gerald Glatt Posted June 22, 2017 Posted June 22, 2017 Com'on guys if they were 'self sharpening' why would they need replaced every year? I'm going with the little man theory, besides it makes such good use of the unemployed guys from the broken refrigerators. 2 Link to comment Share on other sites More sharing options...
