'Threshing sledge' in the Bible

For the dill is not threshed with a threshing sledge, neither is a cart wheel rolled over the cummin; but the dill is beaten out with a stick, and the cummin with a rod.

Look! I will make you into a new sharp threshing sledge, {with} sharp edges. You shall thresh and crush [the] mountains, and you shall make [the] hills like chaff.
