Cuchillería Artesanal El Chaja

El Chaja is a criollo cutlery workshop at Figueroa 1167 in Tandil, the Buenos Aires Province town that has been Argentina's best-known center for handmade gaucho knives since an industrial cluster of cutlerías first formed there in the 1950s. The workshop states forty years of experience and produces the full traditional Argentine range: facones, puñales (daggers), dagas, monteros and parrillero knives for asado, forged from carbon steels (1070, 1090) and stainless steels (420, 440) and heat-treated to a stated 50–52 Rockwell hardness.

Tandil's cutlery trade grew out of the town's stonemasons, who needed harder, more resilient blades for quarry work; that hot-forging and hammer-forging lineage is where the region's reputation for tough, flexible working knives comes from, distinct from the more decorative silver-mounted gaucho knives sold as tourist pieces elsewhere in Argentina. El Chaja's own naming of its product line — facón, daga, montero — follows the working vocabulary of that trade directly rather than a generic "gaucho knife" catch-all.

The business publishes a landline with stated hours, a mobile number, and WhatsApp contact, consistent with a real, currently operating retail workshop rather than a marketplace listing operating under a shop name. It is included as a genuine Tandil criollo cutlería with decades of continuous operation, distinct from the tourist-market gaucho-knife sellers that dominate general web search results for the category.
