The Outward Knifehand Strike is used, for example, in the forms Dan-Gun and Koryo. Note that Koryo uses both Inward and Outward strikes. The difference between and Inward and and Outward knifehand strike is:
- For an Inward strike, the hand finishes palm-up. The arm travels inward to the center of the body.
- For an Outward strike, the hand finishes palm-down. The arm travels outward from the center of the body.
In Do-San, the strike is performed to the side of the body, hence the name Knifehand Side Strike.
