An animated .gif of the process.
Notes: Armor was arguably most elegant in the late 15th century – it’s my favorite period for all things hammered into metal suits. Both Italian and German armor were popular (and used by both Spaniards and Britons). But German armor, like German clothing fashion at the time, was sleeker than the Italian styles. The fluting, as seen here, both highlighted how closely this style of plate fit the contours of the body, and lent strength to the overall structure. This particular set of gauntlets allowed the knight to move his fingers independently of each other in battle, rather than knitting them together into a metallic mitt.
