    I just use a drywall T-square to get a straight square edge and a utility knife. Just be slow and careful

    Another way is with an electric carving knife. I picked one up on sale for something like $15, and it cuts "like buttah".

  4. im going to second the notion of using an electric knife. i got one at target for like $10. i cannot believe how amazing it works. it cuts precisely and perfectly every-time and there's little to no cleanup!

    Either a table saw or a skillsaw will cut the stuff and give you nice clean edges. You can even clamp a straight-edge to the 6 lb. (705) fiberglass.

    Depending on the throat depth BAND SAWS work GREAT! They are what a local company uses for all there fiberglass cutting chores and they even had one build that was big enough to cut out the middle of a 4 by 8 foot piece of fiberglass. This company does a lot of custom fiberglass work for acoustical contractors and they have to make all kinds of non standard cuts to satisfy their clients.
