Mr Shnitzler, in his research lab, started experimenting with various steel blade configurations that would allow for sharper blades to be produced. He, among other things, invented the DE razor blade dispenser with used blade slot, the plastic razor case, the Toggle and Bottom Dial Adjustable razors and he also invented the Silicon coating on Blue Blades which caused them to be renamed Super Blue Blades.Īpparently, on reading the patent application (US2937976) for the silicon coating and news interviews of Mr Shnitzler, men were not adequately prepping their faces prior to shaving and this was causing pain and irritation while using Gillette's product. I came across news articles when researching Meyer Shnitzler (1912 - 2007), the VP of R&D at Gillette from 1933 till 1967.

So, I have been getting more interested in the innovations in razor blade manufacturing technology and why and how those innovations were implemented. Science Magazine Academic Paper - How Hair Deforms Steel

However, heating is essential to PTFE application which Gillette found to be a more important factor in blade durability or shave comfort. Patents have been applied for which will allow for the manufacture of blades which provide more homogeneity by compressing the steel at the blade edge instead of heating it causing less chipping and micro-fractures that lead to edge loss.
