Mary Jane 'Bricktop' Jackson also legendarily roamed the streets of seedy New Orleans and in eight years killed four men. Along with a career in the dance-houses in New Orleans, she was reported to have a favorite knife she designed herself, "it had a heavy five-inch blade at each end, with a center grip handsomely mounted in German silver". Needless to say, she was a complete psychopath, who fittingly had an also-murderous-prostitute roommate, which only could have been the worst possible influence.
Anyway, so back to her knife: with her weapon, she could cut and slash in any direction "without changing the position of her hand," according to her. It's safe to assume that many men fell to her blade before the murder that inspired her disappearance.
In 1857, she moved into a house with Bridget Fury after having been banned from the dance-houses and became a prostitute out of necessity.
In 1861, she "brutalized" John Miller, a former boxer who, get this, lost his left arm in a fight and fastened AN IRON BALL AND CHAIN TO THE STUMP. He made his arm into a mace. You know that REAL men have died out once we live in a time where it doesn't seem reasonable/necessary to attach a medieval weapon to where one of your most important limbs used to be. Oh, the good old days.
As recorded in this book (The French Quarter, by Herbert Asbury), the way everything got started was that Miller (the guy with the Bond-villain arm) threatened Bricktop (the girl with the unsexiest prostitute name ever) with a whip and said she needed to be lashed (while probably wasted out of his mind, or just bored from busting in too many heads with his awesome cannonball-arm).
Bricktop stepped forward, snatched the whip defensively and beat him. He attacked with his iron ball, charging at her and she was able to actually take the ball and use it to drag him down to the floor. As a last resort, he tried to stab her, but she pushed him up against the wall and furiously knifed the beejesus out of him using her pride and joy.
She was sent to prison, released a year later and never heard from again.
