You are far more likely to cut yourself with a dull razor than a sharp one. This is true of knives as well as razors. I also always shave with no cream or gell so I can see what I'm doing. I have incredibly sensitive skin, so have to be careful even with what unscented deodorant I use - I'm even allergic to some "unscented" ones, so I am very careful about what does or doesn;t touch my skin there. A sharp new razor is far safer.
