Am I the only one who cuts batts with a bread knife for tight spots?

It slides through fiberglass clean without tearing. Saves my utility blade for bigger cuts.

Yeah, that's the move for sure. I keep a cheap serrated knife just for fiberglass, stays in the toolbox. The teeth grab the material without yanking it all out of shape like a smooth blade can. You get a much cleaner line around joists or pipes. A utility knife always wants to snag and tear in those tight spots, makes a huge mess.

Watched my friend Dave try that bread knife trick in his crawl space last year. He was struggling with a utility blade tearing up the batts around pipes. Pulled out an old serrated knife and it went through like BUTTER. Said it was a total game changer for those awkward angles. Now he swears by it for any tight spot work.

Truthfully, my only attempt at that was with a box cutter and I just made a horrible fluffy snowstorm of itchy mess in my basement (and probably breathed in something I'll regret in twenty years). I looked like a failed magician covered in glitter, but way, way worse. Dave's bread knife idea sounds way smarter than my whole "hack and cough" plan.
