drumstick
鐻 centers on a drumstick, a tool used to strike a drum. The meaning is narrow and concrete, with no clear abstract extensions.
鐻 combines 金 (metal) with 豦, which likely contributes the sound. The character likely originally referred to a metal drumstick or a similar metal percussion tool.
The left side 金 (metal) suggests a metal tool, and the right side 豦 looks like a complex shape that could be a drum with a stick. Picture a metal drumstick striking a drum.
For キョ, imagine a drumstick striking a drum with a sharp 'kyo' sound: kyo -> キョ, and the metal stick makes that crisp note.
