I've researched more and apparently they're referred to as 'pickle press' or 'vegetable press'. A food press brings results that are like a food mill, which is not what I'm looking for.
I went back to the macrobiotic catalogs and books were I'd first seen this and found the one I linked too previously. But all the ones I find are plastic, and I'm personally not comfortable using plastic for that.
A cheese press seems perfect actually, I'll have to look into that. Thanks MamaLeslie.
The reason I"m looking for this: we often eat cabbage salads where the cabbage is shredded and salted and squeezed by hand. A press would be more efficient at this and I could leave the cabbage in there overnight to ferment some.
