Tandil Criollo Knife Forging and Braided-Handle Work

Cuchillería Criolla de Tandil

The forging, tempering, and finishing of criollo knives — light yet intensively durable blades descended directly from the gaucho facón — in Tandil, Buenos Aires province, a city whose knife-making tradition draws on the ancient Tandilia mountain range's pure water and distinctive climate-driven tempering conditions, factors early master cuchilleros are documented as having specifically sought out. Originally improvised from broken sabers and files by stonecutters (picapedreros) needing exceptionally hard steel tools, and shaped into a genuine industrial craft cluster from the 1950s onward, Tandil's knife-making sits alongside a closely related decorative discipline: the braided rawhide handle and sheath work of named master trenzador Jerónimo Coll, who learned the technique — weaving strands of horse leather over a wooden core before finishing with metal fittings — from his father, the renowned master braider Máximo P. Coll. Since 2000, per named forger Mariano Gugliotta, the craft has undergone a documented national boom, and the municipality, together with the national INTI technology institute and the local metalworking association APYMET, is actively pursuing an explicit strategy to establish Tandil as Argentina's official 'Capital of Knife-Making,' including a formal delegation exchange with Thiers, France's own historic cutlery capital.

Alternate Names
Tandil knife-making
Geographic Center
Tandil, Buenos Aires province, within the Tandilia mountain system, one of the oldest geological formations on Earth; a further named practitioner and family workshop (Keller & Keller) operates in Temperley, Buenos Aires province
Community / Ethnic Group
Criollo (Argentine rural/gaucho-descended) artisan community, shaped by successive waves of European immigrant metalworkers
Estimated Origin
The craft's origin traces to stonecutters (picapedreros) working the Tandilia range, who required exceptionally strong steel tools and, roughly 40-plus years before contemporary sourcing, made their own blades from broken sabers, files, or any other available hard metal, heating and hammer-forging the steel by hand to set the edge; the region's specific appeal to early master cuchilleros — who were drawn to Tandil for the purity of its water and the tempering quality imparted by the climate of its ancient mountains — established the foundation for the city's later industrial knife-making boom, which specifically emerged in the 1950s as Tandil's first industrial knife-manufacturing hub and expanded further following a series of factory openings after World War II
Cultural Function
Explicitly described by contemporary sourcing as 'synonymous with national identity,' with finished knives functioning as 'piezas de culto' (cult objects) born from fire and hammer-blow rather than merely tools; Dick Keller specifically describes working alongside his son as 'the best gift I could have had in life,' framing the craft as a vehicle for family legacy and connection; the municipality's active branding strategy — including the 'Afilada' knife-cluster event and delegation exchange with Thiers, France — explicitly frames the craft as core to Tandil's civic identity and tourism economy
Primary Materials
Carbon steel (specifically documented grades 1070 and 1090) and stainless steel (grades 440 and 420), controlled through modern heat treatment to hardness levels between 50 and 52 on the Rockwell C (RWC) scale, per named workshop Cuchillería El Chaja's own documented specifications; historically, broken sabers, files, and other available hard-metal scrap
Primary Tools
A forge and anvil, for heating and hammer-shaping blade steel; an awl, for Jerónimo Coll's specific horsehide-braiding technique, used to weave leather strands over a wooden handle core before metal fittings are added
Process Overview
Carbon or stainless steel, selected for specific hardness and durability grades, is heated in a forge and hammer-shaped on an anvil into the light, intensively durable blade characteristic of the criollo knife tradition, then controlled-heat-treated to a target hardness range before being fitted with a handle of wood, leather, silver, alpaca silver, or horn — or, for pieces by named master trenzador Jerónimo Coll, finished with a distinctive handle and sheath braided from horsehide leather strands woven with an awl over a wooden core and completed with metal fittings — a craft rooted in Tandil's ancient Tandilia mountain range and actively promoted today through a formal municipal strategy to establish the city as Argentina's international 'Capital of Knife-Making.'
Traditional Applications
Utilitarian tools for stonecutters and rural gaucho use, directly descended from the facón knife tradition
Contemporary Applications
A significant national and international collector and gastronomy-tool export product, spanning a documented wide price range (from roughly $1,200 to $200,000 Argentine pesos as of available sourcing) reflecting individual-maker distinction; a growing formal municipal tourism and international-positioning strategy explicitly modeled on established European cutlery capitals such as Thiers, France
Notable Practitioners
Mariano Gugliotta, named forger and knife expert, quoted extensively on the criollo knife's defining technical and historical characteristics; Dick Keller and his son, of Keller & Keller, Temperley, working together in a home workshop, supplying chefs including Fernando Trocca and the renowned Don Julio parrilla, having evolved from razor-sharpening for barbershops into fine cutlery and gastronomy-tool making; Jerónimo Coll, Tandil, master of horsehide-braided knife handle and sheath work, learned from his father, renowned master braider Máximo P. Coll, whose work has been exhibited internationally; Carlos Allende, an early Tandil knife-shop founder who also created a monument to Fugl, one of the city's first immigrant settlers; Aldo Pedro Manzur ('El loquito de los cuchillos'), an octogenarian who documented this history in a self-published book
