Butterfly blades especially Te newer ones have a squarish portion at the bottom of the handle. It is true that in the picture one can see a silver squarish area, but I see no butterfly logo and from what I see the portion(sticker) is too big to belong to a butterfly blade.
He does use a viscarina with Infinity VPS handle, there was a threat about this earlier with clear pictures of the plies. The plies where either of a Viscaria, Timo Boll Spirit or Timo Boll ALC. But since he used the Viscaria before he singed with Stiga I guess he is still using it.
