- What are the coatings on the razor blades for shaving, and how stable on the blade are they?
How exactly are coatings put onto double edge razor blades (for shaving), how are they put onto the blades, and how stable are these coatings, and how meaningful are they if they are removed after cleaning the blade (like when cleaning the blade after the shave is done)? If these coatings are so easily removed in rinsing or wiping like to take off any remaining hair and soap, then this would seem to change the product quality making the blade have its quality for only a single use, so the intent of the coating seems lost. I do not understand. Can someone who knows about these things explain? The possible choices of coatings are platinum, chromium, ceramics, teflon, maybe others. Stuck on the blades? Attached firmly, loosely? What? How?
