an epee is a three sided blade. The only way I can think of forging one would to be to shape the blade to the shape you want and then use a special spring fuller to put the 3rd side on it. However using a forged epee would be a bad idea unless you can heat treat and temper spring steel perfectly. Even then i would not use it. I use an epee on a fairly regular basis I bought from triplette. If anyone would try using a hand forged epee against me I would have to decline to fight them. I trust Triplette blades over all others but even then they can break and cause serious harm. I had a friend of mine seriously hurt from a broken blade and all fencing stoped for the day. Here is Triplette's website if you would like to buy one
