An ergonomic synthetic rubber compression inlay for maximum comfort and to minimize high-volume fatigue. A precision-machined stainless steel tamper base with TrueTamp rings for a consistent and level tamp. Adjustable handle height - four different handle heights to accommodate the operator's hand size. A flat bottom, 58.40 +/- 0.05mm diameter base – fits the VST Precision Filters perfectly. Tamper base side wall height matches VST filter rim height when filled to design capacity, allowing the barista to quickly confirm by feel if proper weight has been dosed. Anodized Aluminum handle provides a well-balanced, not a bottom heavy tamper.
