What is the most efficient way to remove kernels from a corn cob? I have access to as much sweet corn as I want, so I would like to remove the kernels and store them in the freezer. 

What is the most efficient (low time, high recovery) way to remove the kernels from the cob? I would prefer to get whole kernels if possible. 

I have been using a paring knife, slicing down the sides of the cob onto a cutting board but I find that this slices through most of the kernels, leaving a good bit on the cob and allowing the liquid to escape.
I have read that if you get a bundt pan (see image below) and stick the cob in the middle hole, and then cut the kernels off as you have been, the pan then catches them quite easily. how to get them off the cob without slicing, though, I really do not know.
