The Hyperbolic Crochet is a technique that has always aroused my curiosity.
This particular video concentrates on the making of the Hyperbolic Crochet but adapting it to metal knitting (Tricot with wire).
 
This is a very complete, detailed and straightforward video-tutorial, easy to follow and understand.
