[0303] Not the sharpest tool in the shed

Explanation

A common idiom and euphemism meaning someone is not very intelligent or clever; they are perceived as slow-witted or dull.

Origin

Belongs to a family of idioms using sharpness/dullness as metaphors for intelligence (e.g., sharp mind, dull person).
This specific phrase compares a person to a collection of tools (in a shed, a common storage place for tools), implying they are one of the less effective (duller, less sharp) ones.
Became widely popular in the latter half of the 20th century.
