Metallurgica Motta 8100/M

The Motta 8100/M is the flat-base tamper the manufacturer describes as a stainless steel base with a brown wood handle, in a 58 mm diameter — not to be confused with the 8107/M variant, also stainless steel with a wood handle, which the same catalogue states at 58.5 mm. It belongs to the "Wood & Steel" line of the Metallurgica Motta catalogue, which pairs stainless steel bases with worked wood handles, in the same product family as the 8110/M (52 mm) variant with the same handle.

It is a manual tamper, with no dynamometric or electronic mechanism stated: tamping pressure depends entirely on the user's hand. The manufacturer does not state a weight or handle length on the page, nor whether the base carries any coating or treatment beyond the stainless steel finish.

Metallurgica Motta is an Italian company based in Omegna that describes its output as professional and household stainless steel accessories, and states that laser marking guarantees the authenticity of its own-brand products.
