A foil is a tapered rectangle , whereas a epee is a more like a flat blade thats forged into a V shape, I have lots and lots of broken foils and epee's and that a friend gives me from his fencing studio and let me tell you they are hard stuff, I cant imagine making one that could stand up half as well as a factory made blade. I use the fat end of the blade for cold chisels and punches, and the triplettes are my favoite too
