How to get toddler to use utensils?

My daughter had immediate success with her spoon when she tried it out just before one-year. Other than holding her hand palm-down or in a pincher grip and occasionally turning the spoon upside down to put it in her mouth, she does fine. She can get the food (like yogurt, baby cereal with fruit) from her bowl to her mouth pretty successfully. With her fork, because it is plastic and dull, she has trouble stabbing foods, but can get the right action. My problem is, she usually has no desire to use them. She is 16-months now and when I try to offer her the spoon first thing in the morning, she rejects it and gets angry. After I get a little food in her, I can get her to eat on her own for a few bites, but then she starts just watching the food drip off the spoon (even if she is still hungry) or shakes food off of spoons and forks. If I take it away and try to give it back or try to ist her in adjusting her grip in any way, she gets angry and frustrated and throws it. She's usually such a good-tempered toddler, but is very stubborn about being "helped" with things (she is the same way when I try to help her put pens and crayons the right direction). I know this only gets worse. Any tips to help a stubborn kid 1) be interested in using her utensils for most of a meal; 2) accept instruction/istance on proper grip/motion?
