Yesterday i went to barber shop.i went for shaving.in that process a small cut happened on my face.but he changed blade in front of me.but he didn't cleaned blade handle . chances of getting hiv?

This is a very low risk activity since the blade used for the shaving was a new blade. The HIV virus would not live very long on the blade handle and the blade handle has a low risk of touching you in the cut area. If you remain concerned about HIV, then get an HIV test from your doctor. Good luck to you!

HIV cannot be transmitted through above mentioned mechanism unless fresh contaminated blood on it, the blade was new, just changed in your case. There is still a risk for transmission for other germs and the wound should be watched closely until healed.
