At first glance, people may just think you’re a badass who wears a switchblade as a necklace. But if they only knew that it was actually a sex toy, designed to look like a knife! Doubly badass. The Incoqnito Blade Necklace $125 is not sharp enough to do any damage, because the blade is designed for gently caressing your lover’s bod to make him or her squeal with delight. The hand-cut glass “switchblade” folds down into a black wood case, for concealment during the day. It gives a whole new meaning to tough love.
