Surface Forms

Morphology

dumb + as + a + bag + of + hammers

The comparative template 'as ... as' combined with 'dumb' and the image of inanimate tools (hammers) makes the general idea — extremely foolish — inferable because learners can reason that hammers cannot think. However, the specific figurative choice 'bag of hammers' is an arbitrary, culture-specific simile and therefore not fully predictable from the parts without prior exposure.

Etymology

The saying dumb as a bag of hammers may come from the silly image of a bag full of heavy hammers that just rattle and have no brains. So people use it to call someone 'very foolish'.
