I can’t speak for others, but the first shave is sublime probably due to the new micro bevel and PTFE sitting on top of it. On the second shave you already feel the raw and already (slightly) deteriorated edge, especially after performing three passes. For this reason alone I totally understand others if they use a blade only once.What are some of you doing? Scratching the on cement?
Using a DE blade multiple times is like shaving with a straight razor without stropping it.
