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 you use it. Once you reach the required pressure, the tamper will alert 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 and without unwanted tilting. The spring-loaded mechanism automatically returns to its starting position after being pressed, making the process more comfortable even when preparing larger quantities of espresso. The Ripple Base model features a contoured base with fine concentric circular grooves and a diameter of 58.5 mm, designed to fit standard 58 mm espresso baskets. The construction combines food-grade SUS304 stainless steel and aluminum alloy, while the black finish gives it a clean, professional look that fits seamlessly into both home and café espresso setups.
