You shouldn’t play around with weapons. That’s obvious. At no time, however, is this tougher to follow than when you have a butterfly knife in front of you (okay, being presented with a pair of nunchucks is up there as well). For the addictive joy of flipping one open – without the bodily harm – consider a pair of Butterfly Knife Cufflinks. Not only are these cufflinks functional butteryfly knives, but they’re also a sweet looking accessory for the well-dressed man. Each pair comes with a sharpener so you can keep them ready for use (maybe that wedding is serving miniature prime rib, ever think about that?) and the small lock keeps them closed when you’re wearing them. They’re about a billion times cooler than the black circle cufflinks that come with any rented tuxedo.
