My dad and I just finished working on this so that I could start cooking with my wife. I use a cuff that supports my wrist and allows me to slip right over the end of the knife onto the flat piece of metal that is attached to the handle.
What's special about this set up is that it not only allows me to chop, but allows me to slice with a forward and/or backward motion. I find this important all the time, especially when trying to cut up herbs. The knife hangs from the rod and can be slid from one side of the cutting board to the other. This makes for very flexible cutting service and allows for some interesting techniques.
It's easy, comfortable, and most of all, safe. I hope this helps other quads to get working in the kitchen!
