Cutlery of Thiers

The cutlery of Thiers, a specialized tradition in the Thiers region of the Puy-de-Dôme department, Auvergne-Rhône-Alpes, France, is supported by the presence of the Durolle River and local forests.

Cutlery production in Thiers, first documented in the 13th century, has significantly contributed to the region's national and international reputation in artisanal and industrial sectors. By the 17th century, Thiers merchants exported cutlery beyond France. During the 19th-century Industrial Revolution, production became industrialized. In the early 20th century, cutlers transitioned from using the Durolle River's mechanical power to electricity. By 2016, Thiers accounted for 80% of France's annual knife production, remaining the largest cutlery production center in the European Union and earning the title "capital of cutlery," despite facing industrial challenges and requiring state support.

In 2020, cutlery was the sector with the highest number of jobs in the Thiers region. In 2016, the estimated that the cutlery industry in the city of Thiers employed over 2,000 people. The large proportion of workers residing in the municipality is largely explained by this factor.

Geographic origins In the 15th century, cutlery workshops were established along the Durolle River in Thiers, utilizing water-powered "rouets" (grinding workshops) from the Moûtier district upstream to the Thiers mountains, in areas later known as the Valleys of the Factories and the Rouets. The "parceling out of work" system distributed knife production across multiple sites, leading to the establishment of manufacturing workshops in the medieval city center and nearby villages.

During the Trente Glorieuses (France's post-war economic boom), cutlery workshops and factories began relocating from the Durolle gorges to new facilities in Thiers' lower city. From the 1980s, this expansion included the development of industrial zones, Felet and Racine, near the A89 motorway exits.

History

Origins

The hydraulic power of the Durolle was used in Thiers as early as the Middle Ages to power flour mills, fulling mills for tanners, hammers for papermakers, and, with the development of cutlery, tilt hammers for metalworkers and grindstones for sharpeners. According to legend, crusaders from Auvergne brought back from the East the secret of steelmaking—specifically, the carburizing process. By the 15th century, one quarter of Thiers' workers were cutlers. The objects produced in Thiers were exported to several countries as early as the 17th century: Spain, Italy, Germany, Turkey, and "the Indies."Legrand d’Aussy noted in his 1788 book Voyage en Auvergne that industrialists from Thiers were effectively competing against English manufacturers even in the Indies.

Material sourcing The cutlery industry in Thiers developed primarily due to the Durolle River's hydraulic power and a substantial local workforce. From the Middle Ages, most materials, except wood for knife handles sourced from local forests like Bois Noirs in the Thiers mountains, were imported. Coal was obtained from Saint-Éloy-les-Mines and Brassac-les-Mines in Puy-de-Dôme, while iron and steel were sourced from Nivernais, Burgundy, and Dauphiné. Grindstones were supplied from Langeac quarries and, from the 19th century, the Vosges region.

Organization of the cutlers of Thiers Since the 15th century, Thiers' cutlers adopted a labor division system to enhance production efficiency. Knife manufacturing was distributed across the town, with workers specializing in specific tasks, often passed down through generations, fostering high skill levels. Steel bars were first processed by "martinaires," who thinned them using trip hammers powered by the Durolle River. Blacksmiths then forged the knife components, which were subsequently handled by filers, drillers, grinders, and polishers, who sharpened and polished blades on river-driven grindstones. Manufacturers tempered the blades, while handle-makers provided handles. Final assembly was typically performed by workers in Thiers' suburbs.

Marketing of knives

From the 17th century, Thiers' cutlers employed two primary marketing channels for their knives. Direct sales occurred through cutlery shops established in the medieval city's narrow streets, serving both locals and visitors. Recognizing the potential of the national market, Thiers' high-quality knives were also sold to affluent customers in major French cities such as Lyon, Paris, and Bordeaux. By the 18th century, Thiers expanded into international markets, with merchants gaining prominence in Spain, Italy, and regions referred to as the Indies. The knife trade significantly contributed to Thiers' economic growth, supporting a population exceeding 10,000 by the 18th century and maintaining the region's artisanal vitality. Unlike other knife-producing centers that focused on local sales and were vulnerable to France's economic crises, Thiers' export-oriented approach ensured greater resilience.

Beginning of the Thiers industry

From 1850, the cutlery industry in Thiers adapted to mechanization, enabling its survival and growth while foreshadowing large-scale industrialization. In contrast, paper mills and tanneries, which resisted mechanization, faced declining competitiveness against English and German rivals. By 1860, only about twenty paper mills remained in Thiers, disappearing entirely by the eve of World War I. By the late 19th century, foreign competition prompted Thiers' cutlery industries to modernize through electrification, leading to the development of integrated factories that encompassed all stages of knife production.

During France's Industrial Revolution, which often prioritized mechanization over craftsmanship, Thiers preserved its artisanal expertise in cutlery production. The Durolle River gorges were divided into two valleys. Upstream, the Vallée des Rouets, part of the cutlery museum, opened to visitors in 1998 and maintained traditional artisanal methods using river-powered grinding wheels. Downstream, from 1860, large electrified factories, established after 1900, were constructed along the Durolle's narrow banks in Thiers' lower town.

Working conditions Since the Middle Ages, working conditions in the cutlery industry have been characterized by significant physical hardship and occupational hazards. Grinders, in particular, worked in a prone position to sharpen blades more efficiently, a method that increased productivity but also involved considerable risk. Grindstones, often powered at high speeds by the Durolle River, could shatter violently, with fatal consequences for nearby workers. Environmental conditions in the workshops were also challenging. Located in the gorges of the Durolle, the sites were subject to low temperatures and persistent humidity. In metalworking shops, ambient temperatures could exceed 50 °C, and high humidity was constant. Workers operated powerful machinery, including trip hammers, steam hammers, and cutting presses, which posed serious risks in the event of inattention or malfunction. High noise levels and poor air quality, due in part to coal dust from furnace heating, further contributed to the harshness of the working environment.

Economic crises of the 20th century and production fluctuations

Issues related to water use At the beginning of the 20th century, issues related to the flow of the Durolle River became increasingly significant for the industrial operations in Thiers. During the summer months, the river's flow was low and irregular, limiting the operation of factories dependent on its kinetic energy and leading to periods of underemployment. In contrast, winter brought frequent flooding, as the river became a powerful torrent. Thiers was among the most flood-prone towns in the Puy-de-Dôme department, with the Vallée des Usines being particularly affected.

To reduce dependence on the river, factories began transitioning to electric power in 1903. By 1920, the Durolle supplied an average of approximately 1,000 horsepower per day, while electric power provided around 1,500 horsepower.

This shift allowed local factories to operate more consistently and to function as fully integrated industrial facilities: YearHorsepower1903170190880319141,12319201,200 In 1912, the Durolle Valley employed over 12,000 workers and was home to approximately 550 manufacturers. At that time, the Thiers basin was the leading center for knife and bladed-tool production in France, surpassing other hubs such as Châtellerault, Nogent-en-Bassigny, and Paris, and comparable in scale to Sheffield in the United Kingdom. However, production levels began to fluctuate in the years that followed. YearProduction in tons19123,108 t19181,210 t19202,618 t

Post-war reconstruction Although Thiers remained the leading cutlery production center in France during the 1930s, the post-World War II period saw the emergence of numerous small enterprises. Many workers became self-employed, establishing micro-enterprises that operated alongside the city's larger factories. These small businesses typically employed only a few individuals, often within a family structure. Business owners commonly worked alongside employees in the workshops, while administrative tasks were frequently managed by family members. Workplace relations in these enterprises were generally informal, reflecting the small scale and familial nature of the operations.

Knife production in Thiers continued to grow until the early 1970s. Following the end of World War II, factories such as those at Creux de l’Enfer and resumed operations. During this period, Thiers developed a predominantly cutlery-based economy, with the cutlery industry becoming a central component of the city's economic structure.

End of the Thirty Glorious Years From the early 1970s to the early 2010s, employment in the cutlery industry in Thiers experienced a steady decline. While the sector employed approximately 9,000 people in the early 1970s, this number had decreased to around 3,000 by the early 2000s. Beginning in the 1980s, increased foreign competition—particularly from low-cost Asian manufacturers—led to the permanent closure of many local companies, posing significant challenges for the Thiers cutlery industry.

By the late 20th century, cutlery factories in Thiers underwent further modernization, and the Durolle River ceased to be used as an energy source, having been fully replaced by electricity. Beginning in the 1960s, many companies relocated from the Vallée des Usines to newly developed industrial zones. By 2020, the valley contained numerous industrial brownfields. Some former factory sites, such as and Creux de l’Enfer, were repurposed as museums or , while others, including and , were left abandoned.

Manufacturing

Knife production in Thiers involves multiple stages that incorporate both traditional and modern techniques. The process begins with the selection of steel for the stainless blade, chosen for its cutting performance. This is followed by cutting, which may be performed using mechanical tools, digital laser technology, or stamping methods. Subsequent steps include grinding to form the blade's edge, heat treatment, and quenching to enhance durability and sharpness.

To complete the knife, materials for the handle are selected, which may include wood, corneous, ivory, mammoth tooth, synthetic materials, or metal.

Once both the blade and handle are prepared, assembly and fitting are carried out by hand, particularly within the Confrérie du couteau Le Thiers (Brotherhood of the Le Thiers Knife). The final steps include polishing to achieve the knife's finished appearance, followed by marking and sharpening.
