I dunno, I try to do this with an x-acto knife and something about that plastic still makes it really hard to cut — like a lot of friction with the metal so it doesn't slide without a lot of effort, making it easy to slip and slice yourself. Plus the depth of the plunge is hard, either you wind up cutting two layers (and need some kind of backing), or you try to cut just the top layer but wind up not getting a complete cut.

I hate these packages with a passion. Enough to buy a different product if I have a comparable choice.

EDIT: oh, and then if you take the scissor or just-cut-all-the-way-through approach with a knife, they hide some instructions or manual or small adapter wires between the marketing panels, and then you wind up discovering you've cut those in half too. rageface
