Hi Steve,
There are three power hand tools for cutting sheet metal that I am aware of.
The first is called a “Nibbler”. Drill a hole in your sheet stock, insert the cutting head of the nibbler and move it along your scribed line. It removes small “finger nail clipping” size pieces of metal. These small pieces fall to the floor and imbed themselves in your shoe soles, this makes it difficult to walk on carpets, like at home. This really Pi++++ off the wife, no need to ask me how I know.
This tool would not be at all suitable for cutting hardware cloth.
The second is called a “Unishear” this cuts sheet stock along a scribed line with a small (1/2 to 3/4 inch) up and down blade acting against a bed plate much like a hand “bevel shear”. I don’t think this tool would be at all suitable for cutting hardware cloth but could possibly work.
The third is called “Double Cutters” This is basically a drill motor with a specialized cutting head. Two fingers acting as a bed plate and a third finger (in the middle) cutting up from the bottom. I think this tool would work quite well for cutting Hardware cloth.
But now “you” will be faced with all those little 1/4 inch long pieces of wire on the floor, in your shoes, and in the carpet and Vinyl flooring. Good Luck with that.
Later
Rick
PS.
I have been cutting hardware cloth off and on for 40 years (professionally) and still can’t do it without getting scratched up.
