Tamper base of stainless steel - flat, with protective silicone ring
The tamper base "knock" features a black silicone ring which enables you to gently tap it against the portafilter to shake the coffee grains back into the filter - or to help levelling - before tamping again. This will ensure that your portafilter will remain undamaged.
The manufacturer recommends the "knock" bases to be used in particular with the "Technik" dynamometric tamper handles.
