Morphology
fine-toothed + comb
The phrase evokes a clear visual: a comb with closely spaced ('fine-toothed') teeth used to pick through things, so combining 'fine-toothed' and 'comb' naturally suggests searching or examining very carefully. This compositional, image-based mapping is directly inferable from the constituents, so a B1 learner who knows the words can derive the meaning.
Etymology
Fine-toothed comb comes from that literal tool: to look at something with a fine-toothed comb is to pick out the smallest details, so the phrase means 'to check something very carefully'.
