sickle for cutting grass or hay
鍘 centers on a cutting tool for vegetation: a sickle used specifically for grass or hay.
鍘 combines 金 (metal) with 則, which likely contributes the sound. The character denotes a metal cutting tool, specifically a sickle.
The left side is metal 金, and the right side 則 suggests a rule or pattern. Imagine a metal blade following a set pattern to cut grass evenly.
For サツ, picture a sharp sickle cutting through grass with a quick, decisive sound: satsu! The satsu sound cues サツ while the metal blade slices.
