The Tamper Base Knock Convex features a black silicone ring which enables you to gently tap it against the portafilter to shake the coffee grains back into the filter before tamping again. This will ensure that your portafilter will remain undamaged.
The convex shape ensures that there is more space created between the shower of your group and the compressed coffee grounds. This can improve the water distribution in your filter when using larger amounts of coffee.

This is an excellent base, well made. It has tight clearances between it and the portafilter edges, this can cause a little drag if you like to spin the tamper as you finish the tamping process. This happens when the coffee powder gets in the clearance between the tamper and portafilter. Also the tamping surface is not highly polished as some tampers are. I really like mine, and the small nits are not significant enough to cause any hesitation in highly rating this quality product.

An attractive, simple, knock box. Substantial thickness and weight, plastic, without looking like 'cheap plastic'. The knock bar is quality, good weight and feel, easily removable, yet firmly retained by tight interference fit with the box container. will hold 6 or so double shot pucks. Should last many years of trouble free service, and still look good.

I bought a regular covex base and realized I needed a deeper base. I ordered the knock version since it allowed for more stability while tamping but also let's me knock my portafilter while tamping and has become a must use for me know.
The quality of the tampers are excellent with very fine machining and nice finish.
