The name of a powerful character is just as important as the character itself. “Blechmann” is a name that stands the test of time like a piece of heavy metal. It is also Bernhard Naumann’s moniker, a well-known Austrian customizer.

Defining Customizing

According to Blechmann, he does not consider himself a traditional customizer. As I work, I begin by scraping away at the original painting until just a white canvas is left. The design evolves as the building advances. It’s what I term ‘Blechmann-style quick prototyping,'” explains the customizer. It is what distinguishes his store.

Blechmann is alone artisan and designer most of the time. He may rely on the assistance of specially selected personnel whenever the need arises. It’s impossible to succeed on your own in this world.” “I’m delighted to have a solid staffing infrastructure,” I say.
