The 921 safety razor is precision machined in the United States from 316 stainless steel bar stock. This ensures consistently tight tolerances and results in a much higher quality razor than the traditional casting or metal injection molding processes.  316 Stainless is commonly used in the medical and marine industries as it has superior corrosion resistance, which makes it very suitable for the bathroom environment.  Advantages of the Model 921 Safety Razor: * Machined entirely on CNC (Computer Numerically Controlled) equipment, ensuring accuracy and consistency.
