Flaring

The pressing of metal so that a lip or tail is formed into a compound curve with a concave shape, similar to the mouth of a vase. This technique is essential to making fine quality pieces that are free from the modern danger of being to flat. Barbutes , greaves , crinets , gauntlet cuffs, and vambraces all feature a good deal of flaring, making them difficult to execute. Without doubt flaring is one of the more difficult things for an armourer to learn, but it improves the quality of the resulting pieces by many times.
