If your fingers, or any part of the hammer hit, or the cut, somehow bleeding including these winter dry weather or somehow your peel of your finger nail at the joint, you peeling it very fast. Of course it bleeds.

You always stop the bleeding first. Turn your head away, if too much.

If one drop or 2?

Press it, and wait. And bandage on it. You don't need to disinfect, just the bandage, you see it clearly it dry. You mean you peel your finger and skin, dry. If its a real cut, no, you disinfect.
