The idea of a "pretty gun for a lady" is nothing new. Back in the 1800's a lady of quality would often carry a muff pistol or two when going out for the evening. These deadly little works of art were often set with gems and have gold and mother of pearl inlay. After all, then, as now, you never knew when some ruffian would want to lay their uncouth hands on your money or person.
Having a deadly hidden sting could mean the difference between coming home safe or not coming home at all.
