someone here gave me this link and I corresponded with them. These are 'reverse' dough hooks,
that is they push the dough down.. In Europe it seems all work this way, unlike the stupid hook you get
with a Kitchen Aid. Anyway I have one coming and will post how it performs in a week or so when it gets
its test. They originally questioned what I meant by reverse spiral but that seems to be the only way
they make them even though they never use the word "reverse" on the web site.

Our machine is the Artisan so I am concerned about it taking the load but I have heard that replacement gears are
very cheap so it it takes a new set of gears once a year I won't complain. (much)
