Interesting... look closely and you can see that it is a bench (arbor) press! This is the same tool we were discussing over in the bath bomb thread, with a flat disk attachment on the pressing end. As handy as you are, Tasha, I bet you could buy the $69 version of the bench press for making bath bombs, and rig up the flat disk attachment when you want to knead soap dough.I just saw this cool tool in a sorcery soap dough FB group. For folks with hand issues, this could be great! Thought I’d put it here. NeverKnead polymer clay tool.

Edited: if you look at their parts page, it says right there that it is an arbor press, and that if you have one of those already, they will sell you just the end pieces needed to use it for kneading.
