Some years ago an acquaintance, a UK resident, was attacked by two robbers who used razor blades. He fought them off while sustaining numerous cuts requiring several hundred stitches. During the fray one of the thugs was injured so my acquaintance was charged with assault. He was acquitted but only after a trial and considerable expense. He was later told by "law enforcement" that he was lucky since many thugs taped two blades together to inflict wounds that are harder to sew up and leave serious scars. Lucky him!
I guess we better make all brits grow beards. Down with shaving!
