My only point is that mine doesnt seem to wedge. we do use butternut squash at work and next time i cut one I'll be sure to try the takeda on it. I think the reason for there isnt any wedging is because the big nasty shoulders everybody seems to dislike are pretty asymetric. From a choil view my left shoulder is more pronounced or wider and the right shoulder is maybe 3-4mm taller and much flatter. I think the wedging would occur if the shoulders more even and the bevels similar. But theyre not.
