Here is more about what Hep C is and how it's spread from MedHelp.org. It might help you understand your level of risk.
To transmit Hep c it is required for blood infected with hep c to enter the blood stream of an uninfected person. A surface abrasion is not an open wound. An open wound would be wet and weeping.
From what you described there was no possible entry into your blood stream.

How Is Hep C Spread?
The hep C virus can live outside the body (in dried blood) for up to 3 weeks, say the Centers for Disease Control and Prevention. But in order to spread hep C, the blood of someone with the virus has to come into contact with the blood of a person who doesn’t have it. This can happen either through direct exposure to the blood or by using an item that has been in contact with contaminated blood, such as a hypodermic needle or other equipment used to inject drugs, which is the most common way hep C is spread today.
People once contracted the virus through donated blood (used in transfusions), blood products (such as platelets for people with clotting disorders, like hemophilia) and organs. However, improved screening for hep C in blood products began in 1987; screening was expanded to include donated blood and organs in 1992. Now the risk of getting the virus in these ways is extremely low.
The risk of spreading hep C through sexual contact is also thought to be low, but more research needs to be done. The infection can also spread through personal hygiene products that come into contact with blood, like razors, nail clippers and toothbrushes, though this isn’t common. Pregnant women with hep C have the potential of passing it on to their unborn babies, as well, though the chances are small. Talk to your healthcare provider if you have hep C and have specific questions about your risk of giving it to the people in your life.
Who Is at Risk for Hep C?
While anyone can contract hep C if they’re exposed to the virus, some people are at higher risk than others. It may be surprising to learn that “baby boomers,” Americans born between 1945 and 1965, are five times more likely than others to have hep C.
This is likely because boomers may have been exposed to the virus through contaminated blood, organs or blood products before universal screening for hep C was put in place. Since it’s possible to have the virus for decades with no symptoms, it’s not unheard of to discover you have hep C later in life, long after the infection occurred. That’s why the CDC recommends that all boomers be tested, along with anyone who had a blood transfusion or received a donated organ before 1992, or received a blood product made before 1987.
Others at higher risk include:
People who share hypodermic needles or inject illegal drugs, like heroin
Patients who are on hemodialysis or kidney dialysis for an extended period of time
People who had piercings or tattoos with equipment that wasn’t properly sterilized (this is most common in prison settings; research has shown that hep C isn’t spread in licensed tattoo businesses)
Healthcare workers and others who have been exposed to infected blood and/or contaminated equipment
People diagnosed with HIV or AIDS
Children born to a mother with hep C
People who have unprotected sex with someone who has hep C, or have shared personal items with someone who has hep C
