This tamp takes on a classic shape then evolves to solve ergonomic and aesthetic challenges of many traditional tamps. The wood to metal joint is perfectly smooth and a pleasure for your thumb to rest on. The stainless steel base is precisely machined to 58.3 mm. The removable and replaceable base has a slight taper on the sides and is hand polished to a mirror finish. A natural beeswax and lemon oil finish is applied to the handle prior to the final leather buffing.
