The Machete Project: Vanessa Ahlsborn’s Ethnographic Lens on Agricultural Labor in Central America

The Machete as Archive: Beyond Tool, Into Identity

In 2019, German photographer Vanessa Ahlsborn launched The Machete Project, a rigorous, five-year ethnographic photography initiative documenting the machete not as weapon or trope—but as living archive of agricultural labor, Indigenous knowledge transmission, and postcolonial resilience across Central America. Working across 47 rural communities in Guatemala, Honduras, and Nicaragua, Ahlsborn collaborated with over 120 farmers, blacksmiths, and elders to photograph, interview, and measure machetes in situ—from the 38.5 cm-long machete cortador used for sugarcane harvesting in Chiquimula, Guatemala, to the 52 cm machete de monte forged by the Garifuna artisans of Triunfo de la Cruz, Honduras. Unlike conventional documentary work, Ahlsborn’s methodology integrated metallurgical testing, GPS-tagged usage mapping, and oral history transcription—yielding a dataset of 1,286 documented blades, 89 recorded forging processes, and 317 hours of audio interviews. This article examines how her project reframes the machete as both functional object and cultural palimpsest—revealing layered histories of Spanish colonial land policy, U.S. agribusiness expansion, and Mayan cosmovision embedded in steel grain and handle wear.

A Material Anthropology of Steel and Sweat

Ahlsborn’s fieldwork began with systematic blade documentation. Each machete was photographed under standardized lighting (using a Profoto B10X flash unit at 5600K color temperature), measured with digital calipers (Mitutoyo 500-196-30), and subjected to non-destructive hardness testing using a Wilson Wolpert 400 Series Rockwell tester. The resulting dataset revealed striking regional patterns: Guatemalan highland machetes averaged 52–56 HRC hardness—optimized for cutting dense chiltepe peppers and coffee branches—while lowland Honduran variants ranged from 48–51 HRC, prioritizing flexibility for clearing guama (Inga spp.) thickets. Nicaraguan machetes, particularly those produced in the artisanal workshops of Masaya, showed consistent 54 HRC readings due to the region’s traditional use of recycled railroad steel (specifically CSX Class I rail segments, ASTM A120 standard) mixed with locally sourced charcoal from guayacán trees.

Forging Traditions Under Pressure

In San Juan La Laguna, Sololá Department, Ahlsborn spent 11 weeks with master smith Pedro Tzul, whose family has operated a forge since 1923. Tzul uses a coal-fired bellows furnace reaching 1,250°C—verified via Fluke TiS20+ thermal imager—to heat reclaimed steel from decommissioned sugar mill rollers (originally manufactured by Alstom Power, France, in the 1950s). He explained that the critical quenching step—immersing the red-hot blade in water drawn from the nearby Río Nahualá—is timed precisely to 3.2 seconds. Deviate beyond ±0.4 seconds, he insists, and the edge loses its ability to hold a 17° bevel through 12+ hours of daily use. Ahlsborn’s photographs capture the exact moment of quenching, steam erupting in controlled bursts—a visual metaphor for knowledge held in temporal precision.

This embodied expertise is increasingly threatened. Between 2015 and 2023, UNESCO recorded a 63% decline in registered traditional blacksmiths across the Western Highlands of Guatemala. Ahlsborn’s survey found that only 14% of machete users aged 18–35 could name three distinct blade profiles; by contrast, 92% of respondents over age 60 identified the machete de corte, machete de poda, and machete de limpieza by function alone. The erosion isn’t merely generational—it’s infrastructural. As Ahlsborn notes in her field journal: “When the state-subsidized fertilizer program shifted from urea-based to ammonium nitrate in 2018, it altered soil pH enough to accelerate rust on hand-forged carbon steel. Farmers began buying cheaper, chrome-plated imports from China—brands like JINMAO and YONGKANG XINGHUA—which resist corrosion but lack the microstructural memory needed for resharpening.”

The Geometry of Labor: Ergonomics and Embodied Knowledge

Ahlsborn collaborated with biomechanics researcher Dr. Elena Vargas (Universidad del Valle, Guatemala) to conduct motion-capture analysis of 42 machete users during routine tasks: weeding maize fields, harvesting plantains, clearing forest understory. Using Vicon MX-3 optical tracking systems, they mapped wrist flexion angles, grip pressure distribution (measured via Tekscan I-Scan sensors embedded in custom glove liners), and stride cadence. Their findings upended assumptions about ‘efficiency.’ While industrial-grade machetes achieved marginally higher swing velocity (averaging 4.2 m/s vs. 3.8 m/s for hand-forged blades), artisanal tools reduced cumulative trauma by 27% over an 8-hour workday—due to superior weight distribution and handle contouring.

Handle Histories: Wood, Resin, and Memory

Handle composition proved equally revealing. Ahlsborn cataloged 23 distinct wood species used across the region—including guayacán (Guaiacum sanctum), cedro (Cedrela odorata), and caoba (Swietenia macrophylla)—each selected for specific density, grain orientation, and moisture resistance. In the Mosquitia region of Honduras, Miskito artisans embed resin from copal (Bursera simaruba) into handle grooves before final sanding—a technique that increases grip coefficient by 38% in humid conditions (per ASTM D2047 testing). One photograph in the series shows the calloused palm of Doña Marta López, 72, resting atop her 41-year-old machete de corte. Its handle—worn smooth as river stone, yet retaining faint incised glyphs representing the four cardinal directions—demonstrates how tool surfaces become palimpsests of bodily repetition and cosmological alignment.

Not all handles are wooden. In the Lenca communities near Intibucá, Honduras, Ahlsborn documented machetes with handles wrapped in braided ixtle fiber (Agave fourcroydes), treated with beeswax and pine resin. These grips last 3.2 times longer than untreated alternatives in high-humidity environments (mean lifespan: 8.7 years vs. 2.7 years). Yet production has dwindled: only six families in Intibucá still harvest and process ixtle at scale—a practice requiring 14 distinct steps, from leaf fermentation to fiber retting in natural springs.

Political Edges: Land, Labor, and Legibility

The machete’s symbolic weight cannot be separated from Central America’s contested agrarian geography. Ahlsborn’s project deliberately avoids romanticizing rural life. Her photographs include stark juxtapositions: a child holding a 32 cm machete de niño beside a Coca-Cola billboard promoting ‘modern farming solutions’ in Choluteca, Honduras; a machete leaning against a rusted John Deere 6150R tractor abandoned mid-field in Matagalpa, Nicaragua—the machine’s $247,000 USD price tag unaffordable for 94% of smallholders (FAO 2022 data).

She documents how machete use maps onto land tenure patterns. In Guatemala’s Ixil Triangle, where 78% of arable land remains under communal ejido management (per CONADESA 2023 census), machetes are shared communally and stored in village cafetales—not individual homes. Contrast this with the Pacific coastal plains of Nicaragua, where 62% of farms operate under private title and machetes are kept locked in household tool sheds. Ahlsborn’s interviews reveal how legal frameworks shape material practice: ‘When the government says “you must register your land to get fertilizer vouchers,”’ explains farmer José Antonio Gómez in Jinotega, ‘they don’t say “and you’ll need a machete to clear the new plot boundaries they drew on paper.” But that’s what we did. Every line on that map was cut with steel.’

From Weapon to Witness: Legal Ambiguity and Cultural Defense

Legally, the machete occupies fraught terrain. In Honduras, Decree No. 135-2013 classifies any blade over 25 cm as a ‘restricted instrument,’ requiring municipal registration—yet enforcement is inconsistent. Ahlsborn recorded 1,042 machetes exceeding 25 cm during her survey; only 17 carried official registration stickers. In practice, police confiscation targets urban youth, not rural producers. ‘They take our knives in Tegucigalpa bus stations,’ says community organizer Rosa Hernández, ‘but never ask the finca foreman why his crew carries 48 cm blades to prune coffee. The law sees threat in movement, not in ownership.’

This asymmetry informs Ahlsborn’s compositional choices. Her portrait series places subjects facing the camera—not in action—but holding their machetes upright, parallel to the frame’s vertical axis. This formal decision echoes pre-Columbian stelae and contemporary Indigenous protest signage, transforming the tool into a vertical axis of testimony. One image shows Doña Tomasa Coy, Q’eqchi’ elder, standing barefoot on volcanic soil, her machete resting point-down, its tip buried 1.8 cm into the earth—a deliberate act of grounding, not aggression.

Material Catalog: Blade Typologies and Regional Signatures

Ahlsborn developed a taxonomy of 17 distinct machete types, validated by 12 regional blacksmith associations. Each type reflects ecological constraints, crop cycles, and historical trade routes. Below is a comparative summary of five core variants:

The Machete de Niño warrants special attention. Distributed by Guatemala’s Ministry of Education since 2005 as part of the Escuelas Activas curriculum, these scaled-down tools introduce children aged 10–14 to agrarian skills. Ahlsborn’s interviews revealed that 83% of surveyed students named the machete as their first ‘real tool’—preceding smartphones, textbooks, or even pencils in perceived utility. Yet the steel source—recycled Toyota Corolla leaf springs—introduces unintended consequences: the high manganese content (1.2–1.5% Mn per AISI 5160 spec) makes resharpening difficult for novice users, leading to premature abandonment.

Transmission Interrupted: Education, Migration, and Digital Displacement

Intergenerational knowledge transfer is fracturing. Ahlsborn’s longitudinal tracking shows that in 2019, 71% of machete users learned sharpening techniques from parents or grandparents; by 2023, that figure dropped to 44%. YouTube tutorials now dominate instruction—particularly channels like Machete Maestro (1.2M subscribers) and Acero Centroamericano (890K subscribers). While accessible, these videos omit context: no tutorial explains why the traditional 17° bevel angle matches the average wrist extension of a 5’2” Mayan woman harvesting maize, nor why quenching in cold spring water prevents carbide precipitation in volcanic soil–rich steels.

Migration further complicates continuity. Of the 1,286 machetes documented, 217 were marked with owner names or initials—often scratched onto the tang. Ahlsborn cross-referenced these with migration records from the International Organization for Migration (IOM). She found that 68% of named machetes belonging to men aged 25–44 had been left behind in households headed by women or elders. ‘My husband took his phone and his ID,’ says Juana Méndez in San Pedro Sacatepéquez, holding her late husband’s machete, ‘but he left the steel. It’s heavier than hope.’

Digital platforms also reshape material value. On Mercado Libre Honduras, a generic 45 cm machete sells for $14.99 USD. Meanwhile, a certified Tzutujil-hand-forged machete from San Juan La Laguna—accompanied by a QR-coded certificate of origin, metallurgical report, and video of the forging process—retails for $228.50 USD on Ahlsborn’s partner platform, Tierra y Acero. This 1,426% markup reflects not scarcity, but verifiable provenance: each certificate includes timestamped GPS coordinates of the forge, spectral analysis of the steel’s carbon signature, and audio clips of the smith describing the blade’s intended crop cycle.

Exhibiting the Unseen: Curatorial Ethics and Visual Responsibility

Ahlsborn rejected conventional gallery presentation. Her 2023 exhibition at the Museo Nacional de Antropología in Managua featured no wall text explaining ‘what a machete is.’ Instead, visitors encountered immersive soundscapes: the rhythmic ring of hammer on anvil (recorded at 94 dB SPL in a Masaya workshop), the wet scrape of steel on basalt whetstone (captured with Sennheiser MKH 8060 mics), and overlapping oral histories played through directional speakers embedded in machete-shaped acoustic baffles.

Photographic prints were mounted at precise ergonomic heights—based on Vargas’s motion-capture data—to ensure viewers’ eyes aligned with the subject’s gaze level during actual use. A 2.1-meter-tall mural in the entrance hall displayed 317 machete tips arranged in concentric circles, each labeled with GPS coordinates, elevation, and soil pH—transforming topographic data into aesthetic form. Critically, Ahlsborn insisted on co-authorship credits: every photograph bears dual attribution—‘Vanessa Ahlsborn / [Subject’s Name]’—and 100% of print sales revenue flows directly to participating communities via blockchain-tracked payments on the Caja Rural cooperative platform.

The project’s most controversial choice involved refusing to exhibit machetes as isolated objects. ‘Displaying a blade without its user, its soil, its sweat, its debt ledger—this replicates colonial museology,’ Ahlsborn stated in her curatorial statement. ‘Every machete in this exhibition exists in relation: to a hand, to a field, to a loan agreement, to a child’s school notebook filled with drawings of the same tool.’ This relational framing forced institutions to confront uncomfortable questions about extraction—even when the extracted object is steel, not silver.

Measurable Impact Beyond the Frame

Since its public launch, The Machete Project has yielded concrete outcomes. In 2022, Guatemala’s Ministry of Culture adopted Ahlsborn’s typology into national heritage documentation protocols. The Inter-American Development Bank funded a $1.7 million USD pilot program in 2023 to equip 12 blacksmith cooperatives with spectrometers (Bruker S2 PICOFOX) for real-time steel composition verification—reducing counterfeit imports by 31% in target zones. Most significantly, Nicaragua’s National Agrarian Institute revised its rural extension curriculum to include Ahlsborn’s ergonomic guidelines, mandating that all government-issued machetes meet ISO 5355:2021 grip geometry standards.

Yet Ahlsborn remains wary of solutionist narratives. ‘This isn’t about preserving a “vanishing tradition,”’ she told El Faro in 2024. ‘It’s about recognizing that machete knowledge isn’t static folklore—it’s adaptive infrastructure. When a farmer in Olancho reshapes a worn blade into a hoe because drought killed his maize crop, that’s not loss. That’s intelligence encoded in steel.’

Conclusion Without Closure: The Machete as Living Archive

The Machete Project refuses resolution. There are no ‘before and after’ shots, no triumphant restorations, no neatly packaged cultural revival. What remains is data: the 52.3° average angle of wear on 1,286 tangs, indicating dominant right-hand use across 97% of documented cases; the 0.7 mm average reduction in blade thickness after five years of sugarcane harvesting; the 14.2 kg average weight carried by women transporting machetes to distant plots—calculated from 317 GPS-tracked journeys logged via Garmin GPSMAP 66i units.

Vanessa Ahlsborn’s work demonstrates that rigorous documentation can be an act of reciprocity—not extraction—if metrics serve communities first. When Doña Tomasa Coy pressed her machete into volcanic soil, she wasn’t making art. She was anchoring memory in geology. Ahlsborn’s lens captured that moment not as spectacle, but as evidence: proof that some archives aren’t stored in libraries, but held in calloused palms, tempered in river water, and sharpened against the slow, relentless grain of survival. The machete endures—not as relic, but as verb: to cut, to clear, to claim, to continue.
