that’s right, personally I was never attracted to Hyperion … but the concept of undercut was introduced, much earlier, by Ettore Ferro (B!ST) and according to him that was the way for the future of yoyo; there are many prototypes that he made with this shape often taken to the extreme …
B!ST Futuro
B!ST Mega-Watt
As you can read at the end of the video … “Weight re-balance whit negative-shape (undercut) concept by Mr. Bist”
B!ST Stradivari
and consequently B!ST T.O.G.
I recognize these objects as undisputed works of art as well as pieces of supreme craftsmanship and excellent genius … but the undercut itself, I don’t like it.
