Police issue alert over credit card that doubles up as knife

It’s a new weapon that can be purchased over the internet for as little as €5. The “cardsharp”, as it is described by Portuguese media, is the size of a credit card and can be transformed into a knife. It has already been confiscated by two late-night revellers in tourist spots in Portugal and police warn they are treating it as a “dangerous weapon”. Anyone found with one will face prosecution.
