Morphology

knock + over + with + a + feather

The verb phrase 'knock over' (to knock down) plus the instrument 'feather' creates a clear literal image whose absurdity signals hyperbole; a learner who knows the words can likely infer that something surprisingly strong or shocking is meant. However, the exact idiomatic sense (extreme surprise or stunned inability to react) depends on recognizing the figurative use of an impossible instrument and is a conventionalized expression, so full interpretation is not guaranteed for a B1 learner without exposure.

Etymology

The idiom knock over with a feather shows a person so surprised that even a light feather could knock them over. So it means 'to surprise or shock someone so much that they are almost unable to react'.
