My brother (a contractor) says I should just put a plywood blade into my
circular saw backwards, wear safety goggles and earplugs, grit my teeth
and let 'er rip ... but somehow that sounds a little scary to me on an 18'
ladder.


I've heard of people doing that, but I've never tried it, nor do I plan to.
I'd use a jig saw with a metal cutting blade.
