I wonder if tin snips might work?

Those things cut welded wire and chicken wire like nobody's business.

I do not know if you want to spend the money on expensive scissors but I used the heavy Fiskars Scissors and after putting them in the sun all day I sat down one evening on the patio and they cut very easy.

I had a old pair from my seamstress days. I do not even know if they make them this heavy anymore.
