Today I decided to try to make my own charcoal, there was a lot of smoke in the process, and after about 2 hours my lower eyelids were really swollen, so i put a cold towel on my face for a few minutes, and they got a bit better. It got a bit annoying working with only half sight so I don't want this happening again. Have any of you guys had this problem?

that is über nice...

Is it enough to heat a file to demagnetizing level and then slowly cool it down, or is there any specific temperature for softening a file or metal, this will be my first knife, and I want to get it right, any pointers would be helpful...
