cut, cutoff, be sharp
切 centers on the action of cutting or severing, and by extension the quality of being sharp enough to cut. The meanings 'cutoff' and 'be sharp' are natural applications of this core idea.
切 combines 七 (originally a pictograph of cutting) and 刀 (knife), reinforcing the idea of cutting with a blade.
Seven 七 knives 刀 are lined up, all sharp and ready to cut. Imagine them slicing through a rope, severing it cleanly.
For セツ, picture a set of seven knives cutting in unison: set -> セツ, and the set of blades makes a sharp cut.
