you can't burn a knife... it would cause (the black stuff 'from wich i don't know how to say it in english) it might changes the look by a little, so i've got to stick to fritz' opinion..
The tip of my fruit knife is burnt black.
And the place where the handle and the blade meet is partially melted.
What now?
But as most people said, it is kind of pointless, anything's better than Nexon's crappy knife.
