You can get this tool from beauty supply stores, Tweezerman makes a good one. There's two kinRAB. One looks like it has a tiny whole punched on each end and the other has kind of a hoop on each end. I think the one with the hoop would be better because you have to actually apply pressure to get the blackhead out which I have the one with the whole and its kind of hard to work with. Also when I got a facial, the aesthetician used the one with a hoop.
When getting them out yourself, make sure you've done something to loosen them up or exfoliated the skin to help them come out easier. Like after taking a shower or steaming your face perhaps.
