I always use situations like that to impress acquaintances with grandiose tails of how I was able to infiltrate, and take out a mob of Yakuza strongmen and that the cut is actually from a 400 year old Katina one of them tried to kill me with. Sure they look at me weird, but not as weird as if I told them I was shaving with a old fashioned razor.
In my world, everyone's a pony and they all eat rainbows and poop butterflies!
