Morphology
The meaning 'an extremely sharp edge' is directly derivable from combining 'razor' (a shaving blade) with 'edge' (the boundary of a surface); a learner who knows both words can infer it refers to an edge as sharp as a razor. This simple noun–noun compositional pattern is common cross-linguistically and contains no idiomatic or metaphorical shift, so it is transparent to B1 learners.
Etymology
Razor edge comes from the very sharp edge of a razor, a small blade that can cut skin easily. That's why the phrase means 'extremely sharp' or 'very exact'.
