鞘 centers on a protective covering that encloses something: a sheath for a blade, a case, or the pod (shell) of beans. The margin/difference sense extends from the idea of a narrow gap or space between the covering and what it holds.

Etymology
鞘 combines 革 (leather) with 肖, which likely contributes the sound. The character originally referred to a leather sheath or scabbard.
Meaning mnemonic
Leather (革) on the left and 肖 on the right: picture a leather sheath covering a blade, like a protective case. The same idea applies to bean pods as natural sheaths.
Reading mnemonic
For ショウ, imagine a show of swords being drawn from their leather sheaths: show -> ショウ, and the sheath is the star of the show.
