For the professional barista as well as home users of espresso machines it is essential to use a stable and solid knockbox for the quick disposal of espresso grounds.
The heavier the container, the easier it will be to knock out the espresso puck from the portafilter.
Both knock bar and base should be well damped to absorb the impact on both tools and work surface.
