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.

Comfortable. Period
They are comfortable which is most important for this item. If they’re not comfortable, you’re not gonna wear them but these are comfortable. They fit well and they don’t squish your toes cause they were open. I recommend them.

Great traction on bare floors and no sweaty feet!
I love to wear these with sandals -your feet won't sweat or slide around and you can still show off your pedicure! Great colors also and good value for the price. I did take off one star because one pair (grey)had two left feet!
