hatchet
鉈 centers on a small, single-handed cutting tool: a hatchet, used for chopping or splitting.
鉈 combines 金 (metal) with 它, which likely contributes the sound. The character denotes a metal hatchet.
The left side 金 (metal) and the right side 它 (which looks like a blade with a handle) together suggest a metal hatchet.
For シャ, imagine a sharp hatchet: the 'sha' sound of the blade slicing through wood cues シャ.
