This is a method known as zucken in German. It was taught in 14th -16th century Longsword Fencing manuals. The fencer follows up a long-edge cutting attack immediately with a second false-edge cut (or vice versa), normally at the opposite side of the body. For this reason, the technique only works with double-edged swords, or swords with at least a partial false-edge. This technique requires some training or practice to master, but properly executed it allows extremely rapid follow-up attacks. For example, a cut to the right side of the head might be instantly followed with a cut to the left side of the head. A cut to the top of the head might be followed with a cut to the groin or lower legs, or a cut to the left shoulder might be followed with a cut to the right knee. Very experienced fighters can execute rapid combinations of several true-edge / false edge cuts. Benefit: Gain a +3 Speed Bonus for cutting (Chop or Slash) attacks only with double-edged swords. Gain a +2 Speed Bonus for partial false-edge weapons. Effectively there is no bonus for the initial attack but quite a bit on all subsequent attacks. This feat does not confer extra attacks. Effects replace and do not stack with False-edge Cutting.
