A distinct type of Thrusting Finger Technique which is physically distinguishable by striking in a linear, forward direction - making contact with the tip(s) of the fingers of the hand, palm pointing inward.

Comments:

This strike is most typically effected on a relatively horizontal line, but may be executed on a slight upward or downward slope, depending upon need.

Ideally, this maneuver is enacted with all four (4) fingers, but this is not a requirement.

The ideal execution of this maneuver is at a slightly closer depth than the straight thrust. Most typically, the tip(s) of the fingers would stop at the same depth as the base of the heel of the palm of the straight thrust at the conclusion of its execution.

From one perspective, this is just a vertical thrust punch with the hand open.

As stated above, this strike has a Snapping equivalent which is not specifically called out.

The word vertical, in this case, refers to the orientation of the hand being vertically oriented in relation to its horizontally oriented counterpart - the straight thrust.

Although ideal execution of this maneuver is in a forward direction, it may also be employed to the flank - like the side thrust. This is due to the fact that the naming refers to orientation - not direction.
