I think smooth is a different thing altogether and I'm not about to try to define it.Dovo,
In general I believe I understand what you are saying with regard to pressure= force/surface area.
Getting back to Timeless's warning against pressure. To quote Timeless " This AGRESSIVE 0.5mm blade gap makes for a quick smooth shave. Just don't press. This is our most aggressive razor yet but with the right touch it provides a smooth efficient shave." My take on this is all about risk/reward all under the heading of their most aggressive razor yet. The risk with incorrect touch (technique) leads to blood, irritation etc. With the right touch the aggressive razor provides a smooth efficient shave. I think this implies that their most aggressive razor is capable of giving the most efficient and smooth shave of all of their razors. Why else would someone risk buying their most aggressive razor without the reward of their most efficient and smooth razor.
