i saw a video on you tube and a guy used a chisel/file thing and just hit it like a karate chop and it went down the whole way. . . . i wouldnt recommend this but it looked easy. http://www.youtube.com/watch?v=sQDepqFLpF4 fast forward to 9:00
Actually it works pretty good with large knife or shank of a medium screw driver. Once you snap the first, you can just push down and the it will go all the way down. It is much easier than cutting one at a time.
