This is what my goldfish cutter looks like. Similar to the double flower one, it is mounted on a "handle" for easier manipulation, and also to provide stability to the design while pressing.
This one has lots more detail, including rounded eyes and a cool fantail. The eye circles are soldered to the handle to stay in place. These pictures all show the bottom of the cutter; the part which actually cuts the vegetable. The metal is very thin and gives a nice sharp edge. The eyes are so tiny, though, that the carrot gets stuck...and must be removed with a straight pin :)
