Any lead can smudge if you rub it hard enough.Okay, I only use mechanicle pencils, I don't know what lead type is in them though.
I think that most mechanical pencils have HB lead (at least, that's what this little container of refills is full of). I don't know how soft that is, but it will smudge gradually while I'm sketching.
