As a child, he used to play in the yard with his brother with his father’s blacksmith tools. He also enjoyed modeling and constantly whittling wood, so when he applied for an apprenticeship in carpentry after finishing primary school, it was not surprising. However, he was accepted for artistic craftsmanship in metal processing with a focus on blacksmithing and locksmithing, and within this branch, he apprenticed to become an artistic blacksmith under the guidance of master Ľubomír Karenovič.

In school, he acquired the basics and after completing his military service, he worked as a blacksmith in a company that manufactured fences. Fortunately for his personal development, he was soon accepted for two years into the workshop of the great German blacksmith master Manfred Bergmeister in Ebersberg. The foundation of work in this workshop, where there were four masters among twenty employees, was quality craftsmanship. Mistakes were not tolerated, so it did not matter how many hours a person spent on the job. The result was always important. Every detail had to be precisely crafted while adhering to old blacksmithing techniques. Here, Jozef Tomčala gained a lot of experience, especially learning not to fear restoration, which he still utilizes today. He excels particularly in traditional blacksmithing techniques such as punching, riveting, and riveting, which are highly valued by preservationists when checking the restoration of old objects and their components. In other tasks he is involved in, especially in construction solutions, he also uses more modern welding techniques with flame, electricity, carbon dioxide, or argon, for which he also has state examinations.

Upon returning from Germany, he became a self-employed craftsman with his own blacksmith workshop. He is based in Lehnice near his hometown of Dunajská Streda and specializes in artistic restoration of crosses and old grilles. He creates artistic items from copper, such as spheres and ornaments for churches, and from iron, he makes forged gates and furniture, but he can adapt to any customer’s wishes. Currently, items for households such as railings, grilles, and gates sell best.

Though he only marginally devotes himself to creating items for the Crafts and Art Production Association (ÚĽUV) such as bowls, plates, trays, cauldrons, or sculptures, he enjoys working on them even more. His collaboration with the organization began in 1999 when the chief artist, Janka Menkynová, was looking for an artistic blacksmith to enrich the range of ÚĽUV stores. The designs she had him create were successful and the items sold well, so he continues to produce them with meticulous attention to detail to this day. In addition, he regularly participates in professional events organized by ÚĽUV, such as the Days of ÚĽUV Masters, the Rings on Water competition, the Blacksmith Days at the Crafts Yard in 2004, and demonstrating the craft and lecturing on blacksmithing courses at the Regional Crafts Center in Bratislava. Naturally, he also attends specialized blacksmithing events at Červený Kameň Castle, the Brtnice Blacksmithing event in Brtnice, Czech Republic, and the European Roma Blacksmith Symposium in Dunajská Lužná.

In 2010, Jozef Tomčala was awarded the title of Master of Folk Artistic Production for preserving and developing iron blacksmithing techniques and manufacturing utilitarian copper items
