What is the recommended approach when using a knife edge hand technique?

The recommended approach when using a knife edge hand technique is to position the thumb side toward the body. This alignment allows for optimal control and precision when delivering strikes or performing techniques. By orienting the hand in this manner, the practitioner can effectively utilize the palm and the knife edge of the hand, maximizing the impact while minimizing the risk of injury to themselves during the execution of the move.

Additionally, this technique provides better structural support and alignment with the body's natural mechanics, enhancing overall effectiveness. It also refers to positioning that allows the user to maintain balance and readiness to transition into further defensive actions if necessary. Other placements, such as having the palm facing down or fingers extended outward, might compromise the technique’s effectiveness and the user’s control.
