Morphology

sharp + tool + in + the + box

The phrase combines 'sharp' (intelligent) with a metaphorical comparison to a 'tool in the box', so a learner who knows the constituents can plausibly infer it comments on relative intelligence (sharpest = most intelligent). However the expression is a conventional, humorous idiom used as a mild insult and the specific phrasing/negative usage is not fully predictable from the parts, so it is only partially transparent to B1 learners.

Etymology

The idiom sharpest tool in the box comes from a simple image: a box of tools where the sharpest tool does the best work. So saying someone is 'not the sharpest tool in the box' means they are 'not very clever' or slow to understand.
