About Us


The Hammering Man is a self-taught jeweler and multiple patent holding inventor. Isidro was born in Argentina. At the age of 9, his family immigrated to the United States, where he became a citizen.

Upon earning a Fine Arts Degree from Indiana University, Isidro moved west to Seattle. Happily married with two grown children, Isidro now lives in the woods at the center of the Universe, where he draws his inspiration.

Each work of art is authenticated with Isidro’s hand stamped signature
“I.G. Nilsson” (when space allows).
