Looks like some really nice work though. I would imagine the clientele would be quite different and slightly more sophisticated for a ceramic tamp handle.
So glad you like them Dave! We've been playing around with lots shapes and color schemes over the past few months but the shape and Raffaellesco pattern that dave posted has always been what I was shooting for. Here's a picture of some prototypes with some different classic geometic designs.

Those designs look very reminiscent of the tile work I would expect to see in an Italian kitchen, nice. They would match a tile counter top or backsplash nicely.

Jon, those are a one-off custom. I had a machinist turn the brass inserts from a hunk of 3/4 inch bar stock. Once I get back from my business trip next week I will create a new thread to show them off. I have another set for my lever machine in the works with another wood as well. I don't want to hijack the thread any more than I already have.

Yeah looks great. You should be able to call and talk to Brian or Devon about a piston and threaded insert.

I was googling around and came across this on an Italian site. It's the first time I have seen it. I'm not fond of the looks of it but it's interesting to find there are others playing with force feedback tampers

Here's the Company line:

DYNAMOMETRIC TAMPER (patented)
The dynamometric coffee tamper is a simple device consisting of an aluminium body with a spring inside, replaceable according to the requested force. The extremity of this body there is a shoulder stopping the stroke of the piston, which is replaceable, too.
The piston holds a tamper with diameter on request. The dynamometric coffee tamper is used to solve the problem of the variableness and irregularity in pressing the ground coffee in the coffee filter, avoiding in this way the continuous variations of the grinding on the coffee grinder measurer (which is actually caused by the inconstant pressure of the coffee) and obtaining a more constant product also in the cup. lt is possible to act on the spring or on the stroke of the piston in order to change the force in pressing the coffee.

The main advantages in using the dynamometric tamper are:

Constant pressure on the ground coffee
Uniformity of pressing
Decrease of regulating operations of the grinding
More constant coffee in the cup

I wouldn't be too impressed by a marketing brochure's patent references. Consider for example the concave "original gourmet espresso tamper" (US Patent #D493,338). It's claim is "The ornamental design for an espresso tamper, as shown and described." No claims with regard to function. Zero.

I've admired the style and craftsmanship of Cafe Kultur from afar. Thanks to Teme, who offered to mail me one during his visit the US, I've added this lovely tamper to my collection:

It is deliciously finished and has a unique tapered handle. Thanks Teme, I love it!

Yeah, I love the woods they use. The handles appear to be pretty tall. Is it taller than the RB Bubinga?

Yes, by about one-quarter inch. It's the first piston I've used without a chamfered edge, so the feel it definitely different. My hands are fairly small and yet the knob fits in my palm nicely. Of course it's much better looking than my photo suggests.
