The zeroHero Sword Tamper 58.5 mm is a calibrated tamper designed for precise and repeatable coffee tamping when preparing espresso. The mechanism is factory-set to a constant pressure of 13.6 kg, so it applies the same force every time. Once you reach the required pressure, the tamper alerts you with a distinctive sound. This eliminates the need to guess whether you’ve tamped the coffee sufficiently and makes it easier to maintain consistent results between shots.
The tamper’s design helps guide the base perpendicular to the portafilter, ensuring the coffee puck is tamped evenly without unwanted tilting. The Ripple Base version features a bottom surface with fine concentric circular grooves that create a distinctive circular pattern on the coffee’s surface after tamping. The spring mechanism automatically returns to its starting position after being pressed, making the process more comfortable even when preparing larger quantities of espresso. The tamper has a base diameter of 58.5 mm, and its construction combines food-grade SUS304 stainless steel, aluminum alloy, and walnut wood. The wooden finish gives the tamper a natural and elegant look that complements both home and professional espresso setups.
