Morphology
The meaning 'the sharp cutting side of the blade' is directly and compositionally derived from 'knife' (a cutting tool) + 'edge' (the boundary/cutting side), forming a part–whole noun phrase. This is a regular and cross-linguistically common compound pattern, so a B1 learner who knows both constituents will readily infer the meaning.
Etymology
Knife edge comes from the thin, very sharp part of a knife, the edge where the two flat sides meet, so it means the 'sharp cutting side of the blade'.
