reap, cut, clip, trim, prune
刈 centers on cutting vegetation or similar material: reaping crops, clipping plants, trimming growth, or pruning branches.
刈 combines a crossed shape 㐅 (possibly representing a tool or plant) with the knife radical 刂, suggesting cutting or reaping with a blade. The exact historical origin of the left component is uncertain.
The left side 㐅 looks like crossed stalks or a scythe, and the right side 刂 is a knife. Picture a farmer using a blade to reap crops or trim plants.
For ガイ, imagine a guy reaping a field with a scythe: guy -> ガイ, and he cuts the crops down.
