What's the difference between a joint and a blunt?

I'm curious to know, could you explain the fundamental distinction between a joint and a blunt? From my understanding, they both involve rolling tobacco or paper with some form of marijuana or other herb inside, but I'm unsure of the key differences that set them apart. Are there specific materials used for each, or do they vary in terms of size, flavor, or cultural significance? I'd appreciate a concise yet informative answer that sheds light on this question.
