My one shot, one kill technique was about making the hand, wrist, and pencil function as one unit to follow through the strike like a samurai sword...
The shyt was a sacred art imo. I had my swan attack, where my wrist and arms flowed together in unison harnessing my inner chi. Once I build enough energy I'm smacking TF out of any challenger.
Then I had my power strike, using my thumb as resistance. I'd bend that pencil almost until it would break. Sorta like timing a punt in madden. If done right, the opponents had no chance.
