JoeFrex - 55 mm Tamper Base KNOCK-CONVEX

All the lower parts of KNOCK CONVEX have a slightly convex pressing surface to compress the coffee powder.

Why the name Knock?

After pressing the coffee powder for the first time, lightly tap on the side of the filter holder to dislodge any remaining powder on the sides. Then 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 powder 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 dispensed from it can be evenly distributed over the coffee powder and pass through it uniformly. However, if a flat filter is used in the arm, or if much more than 7g (for a single cup filter) or 14g (for a double cup filter) is used, the space between the coffee powder and the dispensing group may be too reduced for optimal water distribution. For this purpose, you can use the Tamper Base Convex, as it leaves a cavity in the middle of the pressed powder, for better water distribution.

Great little scale!
Color: Stainless Steel, Size: Medium Size
Love this little guy! It's small I use it for all my meals. When in a rush I can just toss it in my lunch box and use it at work. Super convenient. It sits on my counter no bigger than a side plate. Worth the money!

Food scale
Color: Stainless Steel, Size: Medium Size, Color: Stainless Steel, Size: Medium Size
This product is worth the price. The only thing is that it kind of doesn’t work sometimes when you are trying to switch the unit and you might have to double click (as shown in my video) other than that the product works perfect for measuring my food and even my liquids. It’s the perfect size not too big and bulky but it also isn’t that small. As you can see in my picture it’s small enough to fit in my drawer (I don’t like to leave it on my counter) it’s a tiny bit bigger than an Alexa.i also like that the price isn’t to high . I would definitely recommend this product! It’s a sturdy product it doesn’t move when you’re putting any items on it. It’s easy to clean off as well. Another thing is it takes batteries ( it takes AAA batteries, just 2 of them) and I liked how it came with batteries inside of them already .

Lightweight, accurate, and perfect for everyday use
Color: Stainless Steel, Size: Medium Size
This kitchen scale is a great tool for anyone doing meal prep, baking, or tracking food. It’s lightweight and compact, so it doesn’t take up much space and is easy to store when not in use. Accuracy is spot on—it measures consistently in grams and ounces, which is perfect for portion control and precise recipes. The tare function works smoothly, making it easy to weigh multiple ingredients in one container. The stainless steel surface is a nice touch—it looks clean and is easy to wipe down after use. The display is clear and easy to read, even in lower light. For the price, it’s hard to beat. It does exactly what you need without any unnecessary extras. Pros: -Lightweight and compact -Accurate and consistent measurements -Easy-to-use tare function -Stainless steel surface (easy to clean) -Great value Cons: -Small size may not fit very large bowls -Basic features (no advanced tracking) Overall: A reliable, no-frills kitchen scale that gets the job done. Perfect for meal prep, dieting, and everyday cooking.
