There has been some discussion on the alt.usage.english newsgroup about the proper name for this kitchen implement.
I call it an “egg lifter”, but I haven’t always called it that, and don’t remember what I used to call it before.
I checked with my wife, and she said she also calls it an “egg lifter”, but her mother used to call it a “fish slice”.
I don’t really care very much about what they are called. What concerns me is that you can’t get them any more, at least not the design shown in the picture. The new ones all seem to have fat plastic blades rather than thin metal ones, and they also tend to have shorter and wider blades. Our two are getting a bit old, and we keep looking for replacements, but not finding any. We had a fat plastic one before, and it wasn’t much use for frying eggs. It usually broke them.
Anyway, it might be interesting to know what other people call them. Americans on alt.usage.english seemed to call them “spatulas”, but to me a spatula is something used for scraping out dough, and usually with a thin plastic or a wooden blade.
