From 12 feet, you'll throw a full-spin rotation. Grab the knife by the handle, as you would a hammer, but keep your thumb along the top edge for stability and to prevent over-rotation.

你得从12英尺外让刀旋转着飞出去，所以你要像握锤子一样握住刀把，并且让拇指顺着刀刃的方向以保持平衡、防止刀转过头。

If you don't do this, the plane will fall off into a knife edge spin.

假如你做得不好的话，飞机会进入刀刃旋转。
