strike with hand
抃 centers on striking or hitting with the hand, as a direct physical action.
抃 combines 扌 (hand) with 卞, which likely contributes the sound. The exact historical development of 卞 is uncertain, but the character is associated with striking by hand.
The hand radical 扌 beside 卞 suggests a hand striking something. Imagine a hand slapping a flat surface like the top of 卞.
For ベン, picture a bent hand striking: bent -> ベン, and the hand 扌 delivers the strike.
