I had a fascinating idea about hot knives the other day..

Imagine.. electric, glass, knives.

With wires and all...see you'd have to connect the knives in the electric outlet, then turn 'em on..wait a lilttle bit til they get all red and hot.
Then further proceed to successfully assist your buddy who's waiting with a frozen glass cone. (The best I think, is to get a fat vodka bottle and cut the bottom with a glass saw(yea they're real handy) and let it chill in the freezer).

I love knives.

Knife hits with katanas anyone? err... YEA !
