Usually full bearded, but I do have an ancient (so old the handle has turned yellow) ivory handled straight, late 1870s or so manufacture. Belonged to the wife's Civil War veteran great-great-grandfather. I shaved a couple months ago when the heat/humidity became unbearable, first time in years.
Growing back the beard, I'm not military any more.
Do have a cheap dyed bone handled straight for shits and giggles, about a 3 inch blade. Never been used, it's just for looks.
