 Foldforming

Foldforming is a technique of metalworking whereby metal is folded, repeatedly forged and annealed, and unfolded; at which stage it generally has a dramatic new three-dimensional form.While alternate spellings abound (e.g., fold-forming, fold forming, Foldforming, and even form-folding, the definitive book "Foldforming" by Charles Lewton-Brain consistently uses the spelling of foldforming as one lowercase word.
