Bottom
刀 — the indexing radical, picturing a single-edged blade. Declares
剪 a cutting action with a blade: scissors are two blades joined. Same blade family:
切 (slice),
分 (divide),
刻 (carve),
删 (delete). Note the standalone
刀 form is used here rather than the side-radical
刂 because
刀 sits at the bottom of the character.
