Does it throw an arc, or does it work by hammering the point into the metal? I know that there are some "Poor Man's Plans" for the hammering type also, and I think that either one would make for a very fun project.

Congratulations, young man. I must have been in high school at about that time :-)
The Edison pencil, if built as shown, is evidently good for the softer metals, such as aluminum or copper, though since I have a transformer which can deliver twelve volts at eight amps, I'm guessing that I will be able to mark tools with my version.
