Before i switched from the electric torture device to wet shaving i never gave a second thought as to if i had a tough beard or not. Being fare complected and blonde haired (though it's not so blond anymore) I assumed I had sensitive skin and fine hair. Back when i start i tried a variety of DE blades all of which tugged uncomfortably, i settled on Feathers with there reputation of being the sharpest and got rid on the tugging. (A switch to the SR and the problem solved).
Anyway, this lead me to believe i must have a tough beard. Is there a "test" that one could do to verify this? what about sensitive skin?
