Morphology

as + sharp + as + a + butter + knife

This is a straightforward simile using the compositional pattern 'as ... as ...' comparing 'sharp' to a 'butter knife'; since butter knives are commonly known to be blunt, a learner who knows 'sharp', 'butter', and 'knife' can infer it means 'not sharp/ineffective' (often sarcastically). The comparison is literal and follows a cross-linguistic comparative logic, so the meaning is directly derivable from the constituents.

Etymology

As sharp as a butter knife compares something to a butter knife, a dull knife used to spread butter rather than cut food. Because the knife cannot cut well, the phrase means 'not effective' or failing to make a strong point.
