make into mince
劘 centers on cutting or scraping something into very small pieces: mincing, shaving down, or reducing to fragments.
劘 combines 靡 (a phonetic component with meanings related to scattering or spreading) and 刂 (knife), suggesting cutting or scraping into small pieces. The exact historical development is uncertain.
The left side 靡 looks like a scattered, fragmented mess, and the right side 刂 is a knife. Imagine a knife reducing something scattered into even finer mince.
For バ, picture a bar of soap being scraped into tiny shreds with a knife: bar -> バ, and the knife minces it.
