Thunder Espresso Distribution Tool-ZeroHero.

The Zero Hero Thunder Espresso Distribution Tool, often referred to as a WDT (Weiss Distribution Technique) tool, is designed to evenly distribute coffee grounds in the portafilter, ensuring consistent extraction and flavor. It features a magnetic design, making it easy to store and potentially protect the pins from bending. The tool is typically made of stainless steel, with a handle for easy handling and a slim design to avoid direct contact with the needle point.
