JoeFrex - 57 mm Tamper Base KNOCK-CONVEX

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

Why the name Knock?

After pressing the coffee grounds for the first time, lightly tapping on the side of the filter holder to dislodge any remaining grounds. Subsequently, it can be pressed again. 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 integrated silicone ring in 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, the Convex Tamper Base can be used, as it leaves a cavity in the middle of the pressed coffee, for better water distribution.

An excellent book...a must read!
Format: Paperback
Ruthie Gilmore's examination of California's prison-industrial complex paints a sobering portrait of the effects of the state's post-industrial decline in the past quarter century. Supplemented by numerous charts, maps, and statistics, Gilmore argues that the massive prison-building project that began in the early 1980s was rooted in earlier developments, namely the failure of the "welfare-warfare state" to absorb the numerous surpluses created by political and economic restructuring. Combining theory and historical-sociological analysis, this highly readable book is at once depressing and optimistic; it lays out the facts and guidelines for pursuing meaningful, antiracist struggles against the systemic dehumanization of immigrants, low-wage workers, and youths of color that continues to characterize U.S. political culture.

Beautiful Storytelling
Format: Hardcover
In a day and time when gentleness and positive imagination is needed for children, I was moved by this book in the best possible way. The storytelling was restrained and beautiful, allowing the illustrations to carry much of the story. I was truly emotional, in a gentle and grounded way, as I read this story. Every child should have the chance to find their wild side and do it in a safe environment, and this book shows you just how it can feel when it happens. The illustrations are perfect, and gorgeous, and lifted the story up to a new level of enjoyment. I cannot wait to share it with my 6-year-old granddaughter, and I honestly plan to many to give as gifts.
