I always have trouble chopping vegetables like potato, onions for salads real fine. What's the trick?
I use a good chopping knife with no trouble, just cut into workable sizes, place on cutting board and chop away (easiest if you do not lift the point of the knife blade) and you can chop quite a bit in no time.
You are welcomed! You need a sharp knife and one that is big enough that you can use comfortably 
For me I use a Henckels knife that I bought from Target.
