This board is just chock full of helpful people, isn't it?

Drenched- for a fencing foil, you'd probably be better off buying a rod of the appropriate material, which, I'm assuming, would be somewhere in the 1095 or spring steel range.

I'd say start with something around 3/8" round, and shape it gently to a "point" of no less than 3/16". I believe a commercial foil is thinner, but I suspect you'll have difficulty keeping something that thin properly heated.

Heat treating will be tricky, hopefully someone with far more expertise than I have, will chime in with some information.
