It is only the very edge that is SPUTTERED with chromium (and other metals) that allows the edge to maintain it's sharpness and not chip as easily. The PTFE coating is over that edge and is so thin that it buffers the edge and is what imparts the smoothness. Sharpness has nothing to do with smoothness. They are separate factors. The blade is cutting hair THROUGH the PTFE coating as it is molecularly thin.

Thank you for clearing that - but my skin always reacts with blades which have chrome coating. Shark, Wilkinson, BIC, Derby, Schick - thats why I am thinking my skin doesnt like it
Idk for sure and I’m just throwing this out there but some people have a nickel allergy so it could be varying amount of nickel in blade?
