The thing I haven't tired yet, but would like to, is a grit-edged cutting blade in a multi-tool - it might be good for delicate jobs, though not so good to getting into tight spaces.

A variable speed dremel with the 1" round diamond blade worked pretty good for me. It did make fine dust but I wore a mask which should be standard operating procedure when cutting Fiberglas any way

I use a laminate edge cutter which is basically just a small hand held router. Works great with no chipping, real good neat cuts.

Fiberglass Dust!

Just a reminder that fiberglass dust can do a real job of damaging your lungs!

I always try to use a face mask, and a strong fan to blow the dust away from me in a outdoor setting!

I have used a jig saw with metal cutting blades with good results.

A me-too from the former environmental chemist: fiberglass dust is bad stuff. Think silicosis and questionable resin chemistry biology all in one package.

The good news is that it's quite inert, so as long as you wear your PPE and vacuum it up you will be fine.

With the right blade a dremel, jigsaw, and reciprocating saw all work well for precision cuts.
