Traditionally, armourers did not have access to welding torches, so they had to hammer their plates into the desired shape. With a helmet, this requires some very deep forming. Modern craftsmen will achieve complex shaping by making smaller pieces and welding them together. Luke made this helmet in the Italian fashion, with traditional techniques and absolutely no welding, including the hinges and spring pin. Armets are actually five fitted, interlocking plates; the skull, two cheeks, and the the visor, plus the brow reinforce, which covers nearly two-thirds of the helmet skull. This is actually a second steel layer, hammered to fit snugly to the actual helmet skull. Authentic armets also had a rondel mounted at the nape of the neck, a design feature intended to bend, absorbing kinetic energy. It was left off here, for SCA combat purposes.
