'Pruning hooks' in the Bible

And He shall judge among the nations, and shall rebuke many people; and they shall beat their swords into plowshares, and their spears into pruning-hooks. Nation shall not lift up sword against nation, neither shall they learn war any more.

For before the harvest, when the bud is perfect, and the sour grape is ripening in the flower, then He will cut off the sprigs with pruning hooks, and take away and cut down the branches.
