Can you be more specific about what your struggling with? Are you struggling when you try to do very specific cuts like brunoise, small dice, large dice? Are you ok chopping herbs? Is it just with vegetables you struggle with or what about butchering meat, breaking down a chicken, or fileting fish? Are you attempting more advance cuts like food garnishes?
Start very simple. I would suggest a cantaloupe or honeydew melon. Practice first peeling it with your knife. Cut off both ends so you have a flat surface. Then peel the skin with your sharpest knife. I have often used a serrated knife for this it works very well. Once you have it peeled cut the melon in half and remove the seeds. Lay the melon on the cut side and practicing slicing the melon into even cuts. When you slice your knife through be sure to look at the bottom of the melon where the knife will end up so that you keep your slices even.
You can certainly practice on onions or potatoes but you usually end up throwing them out. I like the melon because you can practice and eat what you practice on and avoid waste. The melon is also easier to slice through so you get a little better practicing on a softer material.
Just my two cents.

Can someone tell me if there was any training for the use of a knife in chef's school? Was it extensive or was it simple? Are there any decent books, videos, CD's etc. that I can learn from to see what I'm doing wrong?
Thanks in advance!
