How to cut thin strips of Hardiebacker

I started with Hardiebacker for the first time today for the wall of a shower, and was greatly impressed by the ease of the score-and-snap method for getting the large pieces I need.  However, I also require some thin strips of Hardibacker for a few places (e.g., 3.5 inches wide for the entrance on either side of the curb; 1.5 inches wide in a corner). In those cases there isn't a lot of board to provide much leverage to snap, so how can I make such thin strips reliably?

A:

After scoring, place the sheet on the floor as usual, then cover the thin strip with a stiff board or straight stud as long as the score line. Align one edge of the board with the score. Kneel, or have someone stand, on the board. Pull up on the larger piece. 
In other words, score and snap as usual, but trap the thin piece between your work surface and a stiff strong board.
