What’s the key to being a sharp dresser? Knives, duh. (Just like how fire is the key to looking hot.) These butterfly knife cufflinks will make your wardrobe just a tiny bit sharper, not to mention more dangerous. As in, dangerous to wear to the airport or court or any place with a metal detector where you might get tackled by police. Made from stainless steel, each cufflink measures 1” long closed and 1.5” long opened. The set also includes a sharpener so you can keep the blades ready for action. “Ready for action” probably meaning “ready to cut loose threads or clean under your fingernails,” but to be fair, you never know when you might get into a knife fight with some Borrowers.
