Just found this thread today and am very thankful. My fingers and hands can be an extreme source of frustration for me on a given day.
I have had times when DH has had to cut the meat on my plate for me. I've noticed the stares. I'm sure some think I'm acting like a diva and some think how cute it is that he's cutting my food for me.

Of course, I also get the stares in public when I'm having difficulty cutting (fumbling) my food. Can't win. What do I do at home? Stab it with a fork and go all "cavewoman" on the food. LOL
That onion thing is very cool and looks like what I do with a fork already. I don't do well with cutting food but if I can hold it steady, it's easier.
Bummer about the Tater Gloves though because it takes me forever to use a veggie peeler.
