I am new to shaving with a safety razor. (I'll never go back to cartriges) I have always shaved with cold water because someone explained the physics of temperature and steel to mewhen I was very young. It makes sense that cold water will keep the molecules tightly packed or bunched together therefore resulting in a sharper edge. Seems that heat would cause the steel to expand and would compromise the integrity of the edge. What do you guys think? Am I wayyyy overthinking things?
