The chainmail mace you are referring to was purchased as a gift for me from a vendor at Dracula's Ball in Philadelphia that specializes in chainmail clothing, armor and accessories. I have yet to find a submissive willing to experience it!
Who doesn't love a good flogging, but a good flailing? Is that an oxymoron? It's gorgeous in any case and I'm sure some sturdy sub will eventually brave it for your amusement ;)
