Gustavo Cunha, maker of Martelo pipes, is a nature and wood lover since he was a child. Born in Diamantina-1987, an old colonial village in the Minas Gerais State of Brazil, he had access to traditional wood turners that guided him to study & graduate in design. After he worked in a Brazilian modernist furniture design office. There he had the chance to make some sketches and make briars for his friends, starting with freehands derived from classic shapes.

After visiting Eltang (Denmark) in October 2013 he began to consider pipe making as a profession and only one month after that he bought all the equipment for his own workshop and became a full-time pipemaker. Recently he spent some time with Chris Asteriou and Konstantinos Anastasopoulos (Greece) honing his craft, and readily admits he was influenced greatly by the young Greek's work.

Gustavo Cunha uses only super dry Greek (Makis Minetos) and Italian (Mimmo Romeo) briar blocks
