Types of Arm Attacks

Three types of delivery:

• Snap. A snapping motion, similar to snapping a bullwhip, to the surface of the target. The attack only penetrates a couple of inches and is then snapped back into chamber. 
• Push. Pushing into or through the target.
• Snap-push. Combining the snap and push. An advanced technique that may cause internal damage with little external damage. Such as rupturing an organ while not leaving a bruise on the skin. The technique may be used in board breaking to leave the first board intact while breaking the others.

Four types of motion:

• Linear. Hand moves straight at target.
• Hooking. Hand arcs and moves in a semicircular motion to the target.
• Dropping. Hand moves in a downward motion into the target.
• Rising. Hand moves in an upward motion into the target.

Inverted Technique. An inverted technique is one where the striking body part is turned upside down. For example, an open hand strike with the palm up using the outer edge of the palm is a knife hand strike; whereas, an open hand strike with the palm down using the outer edge of the palm is an inverted knife hand strike.
