There are two varieties of foil in use today: the "dry", or nonelectric, foil; and the electrically scored foil. The components common to both varieties are the pommel, grip, guard, thumb pad, and blade. The nonelectric foil has a real tip with a blunted end that is capped with a plastic or rubber knob.
The electric foil also contains a socket underneath the guard that connects to the scoring apparatus via the body cord and a wire that runs down a channel cut into the top of the blade. The tip of the electric foil terminates in a button assembly that generally consists of a barrel, plunger, spring, and retaining screws. The circuit is a "normally closed" one, meaning that at rest there is always a complete power circuit. Depressing the tip breaks this circuit, and the scoring apparatus illuminates an appropriate light: white for hits not on the valid target area, or either red or green representing hits on the valid target area.
The pommel, a type of threaded fastener used to fasten blade, guard, plug, and grip assemblies together, is specific to the type of grip that is used. There are two types of grips used for foils: straight grips with long, external pommels, comprising the French, Italian, and Spanish varieties, and orthopedic, or pistol grips, which are designed to fix the hand in a specific position and have pommels that fit into a countersink in the back of the grip. Electric foil plugs are fixed so that the body cord plugs into the weapon along the inside of the wrist. There are two varieties in use today: the two-prong variety which has unequal diameter prongs and is held in place by a retaining clip, and the single-prong Bayonette which twist-locks into place. Foil guards are limited to a diameter of 9.5 to 12 cm in international competition.
