Swords into ploughshares

"Beating swords into ploughshares" is the conversion of military weapons or technologies for peaceful civilian applications. The phrase originates from Isaiah 2:4:
The ploughshare is often used to symbolize creative tools that benefit humankind, as opposed to destructive tools of war, symbolized by the sword, a similar sharp metal tool with an arguably opposite use. The rest of the passage similarly equates spears with pruning hooks.
In addition to the original Biblical Messianic intent, the expression "beat swords into ploughshares" has been used by various pacifist movements.
A past example from the period 1993 continuing to 2013 is the dismantling of nuclear weapons and the use of their contents as fuel in civilian electric power stations, the Megatons to Megawatts Program. Nuclear fission development, originally accelerated for World War II weapons needs, has been applied to many civilian purposes since its use at Hiroshima and Nagasaki, including electricity and radiopharmaceutical production.

Biblical references

Beyond the above usage in the Book of Isaiah, this analogy is used twice more in the Old Testament/Tanakh, in both directions. In Micah, it is recited word for word:
In Joel, the opposite is said:
An expression of this concept can be seen in a bronze statue in the United Nations garden called Let Us Beat Swords into Plowshares, a gift from the Soviet Union sculpted by Evgeniy Vuchetich, representing the figure of a man hammering a sword into the shape of a plowshare.

From the 1970s onward, several anti-war musicians have played guitars made from military surplus weapons. Jamaican reggae star Peter Tosh famously owned a Fender Stratocaster built around an M-16 rifle.
