JoeFrex - 58 mm Tamper Base KNOCK-CONVEX

All KNOCK CONVEX bottom parts have a slightly convex pressing surface to press the coffee grounds.

Why the name Knock?

After pressing the coffee grounds for the first time, lightly tap (from English Knock) on the side of the filter holder to dislodge any remaining grounds. This allows for subsequent pressing. To avoid using the base of the tamper or the wooden handle for this light tap on the filter holder, risking damage to both the tamper and the filter holder arm, you can now tap with the silicone ring integrated into the base.

Why the name CONVEX?

Normally, the surface of the coffee grounds pressed into the filter holder doesn't play a significant role; whether it's flat or concave, there's enough space between the coffee surface and the dispensing group so that the water can be evenly distributed over the coffee grounds and pass through them evenly. However, if a flat filter is used in the arm, or if much more than 7g (for a one-cup filter) or 14g (for a two-cup filter) is used, the space between the coffee grounds and the dispensing group may be too small for optimal water distribution. For this purpose, you can use the Convex Tamper Base, as it leaves a cavity in the middle of the pressed coffee for better water distribution.

Practical and pretty
Color: Silver
This is a three pocket purse. One top zipper covers all pockets. It is the only evening bag I own that has enough room for all my stuff. At my age I need more than a comb and a credit card and keys. The crossbody chain is pretty and does not look cheap. I wear purses this way so that my hands are free to do what I want, like dance, go through a buffet line, stand and talk, etc. Even though this is not a costly bag, it does not look cheap. I would recommend this without reservation.
