PURPOSE: A functional nail is provided to allow the functional nail to be easily removed by including an additional head plate of a nail. CONSTITUTION: A functional nail includes a body(12), a head plate(14), and a support head plate(16). The head plate(14) is formed on the upper end of the body(12) and delivers force generated by a hammer. The support head plate(16) is separated from the head plate(14) with a predetermined distance and pressurizes the support head plate(16) when the hammer hits the head plate(14). The body(12) has a wedge shape so as to easily be driven into support wood plates. The body(12) includes steel, wood, and resins. The head plate(14) generally has a shape used for a nail. The head plate(14) includes materials different from the body(12).
