How long can an HIV virus live outside the human body on a sewing pin?

let me paint the scenario, a person sewing pins on several pin on chest corsages and pricked her finger. later, A HEW HOURS LATER a person wanted to attach the corsage on his chest and pricked his finger. is it possible to get infected assuming that the first person has HIV?? note: it happened several hours later, the pin was semi wiped as it passed through the shirt before it reached the other persons finger. and there was no VISIBLE blood in the pin (since it's not visible it cant be a lot) how long would the virus be infective??
