Cool Material puts a dangerous spin on a noble menswear accessory. The butterfly knife cufflinks offer a functional butterfly knife on a cufflink. Each pair comes with a sharpener so you can have a piece of cutlery (or a weapon) handy whenever needed. Will you get in trouble for wearing them through an airport check? Possibly, but why not live on the dangerous side for once?
