Will I spread my toenail fungus by doing this?

Hey guys. I'm 20 & have had (what I believe) is toenail fungus for about 2 years. I have always used the same clippers for my feet, and fingernails. After reading it can spread it, I tried to disinfect the clippers with witchhazel (it contains 14% alcohol) I'm not sure if it did any good though. I haven't notice any areas of my fingernails which look like they may be infected, they look perfect. How much of a risk am I at if I stop using the same clippers? Thank you!
