Brass knuckles can come in super-handy during a fight, as you tend to automatically earn everyone's respect when you unleash a CD with Nelly and special guests Nate Dogg & Gucci Mane. They also come in handy for making your home look completely sweet, thanks to MAD Design Group. From a Miami-based luxury-home maven who recently completed an overhaul of Electric Pickle/The Bolero Room, just-launched MAD pumps out a line of man-tastic lighting fixtures by "upcycling" dangerous items like knuckle dusters, and even more terrifyingly...books! Some showstoppers: Bully: Basically the coolest chandelier ever, it's made of 70 sets of brass knuckles Mark fastened together with nary a weld. The brass version's equipped with bulbs whose tips got a bath in chrome, while there're old school Edison bulbs on the copper model, also how they denoted Heather Locklear in the T.J. Hooker scripts. Crank Down: These're smaller, cheaper, glowing-filament light fixtures dangling from recycled bike parts, like cogs and chain rings, aka, the very people who tricked you into mailing 36 friends handprinted letters, just to ensure your ferret didn't get colon cancer. Dominant Disclosure: Mark's studious table lamps're assembled by jamming a multi-filament glow bulb into a set of vintage law books that've been pile-drilled, but not pile-driven, as that's handled by Brett "The Acquit-Man" Hart. Mark's also doing custom brass knuckle drawer handles in chrome, steel, and brass, collectively called "Pull Hard", the very action you must take when you notice Brass Knuckles about to slide into your CD changer.
