I talked to a karate fighter who participated in a study in which the karatekas had higher punch output when their straight punch arm was bent compared to extended. This was a surprise to them.
Could it be that there's greater bicep engagement when the arm is bent compared to straightened out? Also perhaps stronger wrist support at the point of impact?
Might want to look at kinetic chains and methods of momentum transfer. 'Bicep engagement' is part of what is known as force couples.

While the biceps are not the primary muscles in the force couple generating rotational power, they play a supportive role by:
Assisting with Elbow Flexion: During the preparatory phase or chambering of the punch.
Stabilizing the Arm: Ensuring that the elbow joint remains stable and aligned during the punch, which indirectly supports the rotational force.
Aiding in Retraction: Helping to bring the arm back after the punch, preparing the body for subsequent movements.
