Oh noes, the F word, you win teh argument and the internet.
My point was its a dumb weapon because he loses the element of surprise in terms of manouverability of the flames. In a sword they are compressed in one line, it takes away the whole awesome effect of him just looking at something and it burning up. They both use chakra, but a sword is a rubbish way to use it.
And I didn't call you names, so don't do so to me. Its childish.
