May have knocked blood blister on man and little bleeding cuts on hands what's the chances I will get hep c or hiv?

Not likely. It is unlikely to get hepatitis c or HIV from brief exposure to blood. Of course it is impossible to get hep c or HIV from a man that does not have the virus in the first place. Hopefully you know this man and can ask him if he has hepatitis or not. Hepatitis b is much more contagious, and there is a vaccine for this, so see your doctor and make sure you are immunized!
