Seeing as you can only wear, like, 10 mood rings at a time, there's Karen Keith: a Big Apple transplant who turns out everything from necklaces dangling rusted wrenches to pocket knife bracelets, and just opened a Downtown dungeon-meets-den-of-iniquity studio/shop whose black walls are lined with vintage mirrors and whose works hang off everything from headless mannequins, to Texas Chainsaw Massacre-esque farm tools, who actually end up living much longer in those movies than the cool kids who do awesome boning. The goods:
Hardware Line: These suckers throw antique drum keys, worn-down wrenches, and locks onto thick silver or muted gold chains, also what you call watching a rap video with no sound on.
Key Line: Also looped around woven rope-like chains, or attached to actual keyholes, these diddies range from standardish door-openers to massive gold keys that look like they could very well open the door to Narnia, assuming you're also willing to undergo the rather invasive surgery to repair your now-ravaged childlike sense of wonder.
Other Stuff: She's also got antique pocket watches strung as bracelets and long necklaces, some of which feature exposed guts, just like those losers they kill off once all the attractive sexually active people are done for.
