'Pruning hooks' in the Bible

He will judge between the nations, and will decide concerning many peoples; 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 blossom is over, and the flower becomes a ripening grape, he will cut off the sprigs with pruning hooks, and he will cut down and take away the spreading branches.
