Weapons are the classic double‑edged sword: forged to destroy, yet they can be reshaped into tools of peace. In this roundup of 10 peaceful items, we explore how deadly armaments have been creatively repurposed into guitars, sculptures, power sources, farm gear, and even kitchenware. From battlefield rifles turned into musical instruments to decommissioned warships recycled into cookware, each example shows how humanity can turn swords into plowshares.
1 Pots And Pans
Ships are essentially massive steel structures, and when their service lives end, about 95 % of that metal can be reclaimed and melted down again. This recycling rate includes even the most heavily armed vessels, which are stripped, cut, and re‑forged into brand‑new products. Among the countless possibilities, the scrap metal can be rolled into kitchen essentials such as pots, pans, and other cookware.
One notable example is the British warship HMS Invincible, a famed carrier that saw action in the Falklands, the Balkans, and the Iraq wars. After decommissioning, the navy sold the hull to Leyal Ship Recycling in Turkey for a modest £2 million (roughly $3.2 million). The transaction, conducted over a simple online listing, sparked eyebrows but ultimately ensured the ship’s metal would find a second life.
Although the idea of turning a warship into kitchenware sounds poetic, the reality of dismantling such massive steel hulks is fraught with danger. Cutting through armor and thick plating requires specialized equipment and exposes workers to hazardous conditions; each year, a tragic number of laborers lose their lives while slicing old vessels into bite‑size pieces.
2 Chemotherapy
World War I earned the grim nickname “the Chemist’s War” because chemists on both sides engineered lethal gases such as chlorine, xylyl bromide, and the infamous mustard gas. Mustard gas, first unleashed by Germany in July 1917 at Ypres, Belgium, inflicted devastating injuries on roughly 10 000 Allied soldiers in a single assault, with countless more suffering severe burns, blisters, and respiratory damage.
Unlike other toxic agents, mustard gas could penetrate gas masks and even thick clothing, entering the body through the skin. Victims endured excruciating coughs, blistered flesh, and a slow, agonizing death that could take up to six weeks. Decades later, as the world braced for another global conflict, researchers at Yale University—Louis Goodman and Alfred Gilman—noticed that soldiers exposed to mustard gas showed a marked decline in white blood cells.
Turning tragedy into triumph, the duo hypothesized that the same chemical could be weaponized against cancer cells, which arise from mutated white blood cells. Their experiments with nitrogen mustard demonstrated that the compound could eradicate leukemia in patients, laying the groundwork for modern chemotherapy. Thus, a weapon of mass destruction became a cornerstone of life‑saving medical treatment.
3 Headphones And Wristwatches
Swedish nonprofit IM partners with governments across Latin America to extract illegal firearms from the streets and transform the recovered metal into what it calls “Humanium metal.” This recycled alloy finds its way into sleek consumer products, turning instruments of violence into symbols of hope.
In 2018, IM teamed up with Yevo Labs to launch a limited‑edition version of the Yevo 1 wireless earbuds. Parts of the earbuds and their charging case were forged from Humanium metal sourced from seized firearms, giving listeners a tangible reminder that peace can emerge from conflict. The same year, IM collaborated with watchmaker Triwa to craft a line of wristwatches, each incorporating metal from guns confiscated by Salvadoran police.
Both the earbuds and watches serve as wearable statements: they embody the idea that the very metal once meant to end lives can now accompany you on a jog, a commute, or a night out, all while sparking conversations about disarmament and social responsibility.
4 Garden Tools
The ancient proverb “swords to plowshares” finds a modern incarnation in the RAWtools program, a Christian‑run nonprofit dedicated to curbing gun violence by converting firearms into agricultural implements. So far, the organization has reshaped AK‑47s and AR‑15s into spades, plows, hoes, mattocks, and trowels.
Each surrendered weapon is first stripped of its components, then melted in a furnace. The molten metal is poured into molds, and volunteers—often victims of gun violence themselves— hammer the cooling metal into functional farm tools. This hands‑on process not only recycles the metal but also provides a therapeutic outlet for participants, turning trauma into tangible, useful objects.
RAWtools founder Mike Martin cites an Old Testament verse that envisions a world where weapons become farming tools as his inspiration. The program only launched after the tragic Sandy Hook elementary school shooting on December 14, 2012, which claimed 28 lives and wounded two others, underscoring the urgent need for creative solutions to gun‑related tragedy.
5 Artificial Reefs
Coral reefs are the bustling underwater metropolises that sustain countless marine species, yet they’re under siege from climate change and human activity. Governments worldwide have begun sinking decommissioned vessels—subway cars, oil rigs, and even military hardware—to create artificial reefs that foster marine life.
Jordan has taken a uniquely bold approach by sinking an array of retired weapons, including tanks, armored vehicles, and helicopters, off the Red Sea near Aqaba. These decommissioned pieces now rest 50 to 90 feet beneath the surface, forming a burgeoning habitat for fish and coral while simultaneously serving as an underwater museum for divers.
As of July 2019, the Jordanian program had already placed 19 weapons on the seabed, with plans to expand the collection. The dual purpose—marine conservation and tourism—illustrates how even the most destructive tools of war can be repurposed to nurture life beneath the waves.
6 Knife Angel
The Knife Angel, officially titled the National Monument against Violence and Aggression, towers at 27 feet tall in Hindlip, West Mercia, UK. Crafted by the National Ironworks Center in Oswestry, the sculpture is forged from an astounding 100 000 knives and blades confiscated by police from crime suspects across the nation.
Approximately 30 % of those blades still bore blood when they arrived at the workshop, underscoring the stark reality of knife crime. The sheer volume of seized weapons even allowed the center to conceive a second monument—a tribute to police dogs—made from dog whistles, tags, and gun parts, celebrating the bravery of four‑legged law‑enforcers.
Installed outside the West Mercia Police headquarters, the Knife Angel serves as a solemn reminder of the human cost of blade‑related violence while simultaneously turning the instruments of that violence into a powerful piece of public art that encourages reflection and dialogue.
7 Tractors
In the aftermath of World II, French agriculture faced a dire crisis: battle‑scarred fields riddled with craters and a severe shortage of functional farm machinery. The Nazis had either destroyed or shipped away the country’s tractors, leaving farmers stranded.
The French army answered the call by converting roughly 3 000 surplus Renault FT‑17 tanks—originally designed as light armored combat vehicles—into makeshift tractors. Stripping away armor and armaments, engineers added simple implements, transforming the hulking machines into reliable, low‑cost agricultural workhorses.
This conversion proved a win‑win: it rescued France from potential famine, supplied farmers with affordable tractors, and allowed the military to off‑load obsolete tanks. As French soldiers told the farmers, “Those little tractors that whipped the Hun will undo much of what the Hun has done,” a nod to the German occupiers.
8 Electricity
Many Americans are unaware that, for a decade, Russia supplied roughly one‑tenth of the United States’ nuclear‑generated electricity. The story began after the Cold War, when the two superpowers agreed to dismantle portions of their nuclear arsenals.
In 1993, the United States and Russia signed the U.S.–Russia HEU Purchase Agreement, obligating Russia to reprocess uranium from decommissioned warheads into low‑enriched nuclear fuel. This fuel was then sold to the U.S., where it was fabricated into fuel rods to power American nuclear reactors.
The arrangement proved profitable for Russia—turning disarmament into a revenue stream—as Anton Khlopkov of the Center for Energy and Security Studies noted, “This is the only time in history when disarmament was actually profitable.” The deal concluded in 2013 when the final shipment of fuel arrived in the United States.
9 The Throne Of Weapons And The Tree Of Life
Mozambique endured a brutal civil war from 1977 to 1992, leaving over a million dead and five million displaced. In the war’s aftermath, the government launched the “Transforming Arms into Tools” program, encouraging former combatants to exchange their weapons for agricultural implements, ultimately retrieving an astonishing seven million arms.
In 2001, Mozambican artist Cristóvão “Kester” Canhavato welded a selection of these surrendered weapons into a striking sculpture he named the Throne of Weapons. The piece incorporates rifles and magazines from a variety of origins—Western, Russian, Portuguese, and North Korean—symbolizing the diverse sources that fueled the conflict.
Another collective of Mozambican artists created a three‑meter‑tall Tree of Life, also fashioned from the recovered arsenal. Unlike Kester’s exclusive focus on assault rifles and magazines, the Tree incorporates pistols, rocket‑propelled grenade launchers, and other weaponry, forming a vivid tableau that juxtaposes destruction with renewal.
10 Escopetarra
The escopetarra—literally “shotgun guitar”—blends the worlds of music and armaments in a strikingly literal way. Though its name hints at a shotgun, the instrument is actually crafted from decommissioned assault rifles, most commonly AK‑47s. Colombian musician César López conceived the idea after witnessing a tragic car bomb in Bogotá that killed 36 people and injured 170.
At the blast site, López saw a soldier cradling his rifle as if it were a guitar, sparking the notion that the weapon could be transformed into a musical instrument. He began converting surrendered rifles—recovered from Colombian militias—into functional guitars, a practice he continues today.
Each escopetarra carries a powerful message: weapons designed to silence can instead amplify harmony, turning instruments of war into symbols of peace.
