manage, do, handle, deal with
辧 centers on taking charge of a task: managing, handling, or dealing with something actively.
辧 is a variant form of 辨, combining 辡 (two 辛, possibly representing two sides or a dispute) with 刀 (knife), suggesting dividing or managing with a knife. The exact historical development is uncertain.
The outer 辡 looks like two sharp sides facing each other, and the inner 刀 is a knife. Picture using a knife to separate and manage two conflicting sides.
For ベン, imagine a manager named Ben who handles everything with a knife: Ben -> ベン, and he deals with all the tasks.
