There's a Reciprocating Saw Blade Made Just for Drywall — Use It for Demo

The Problem

Cutting drywall for demo or access with whatever blade is in the recip saw is the standard move, and it's the wrong one twice over: a long wood blade plunges way past the back of the drywall into the stud cavity — where the wiring and plumbing live — and its tooth pattern chews the paper face into fuzz instead of cutting a clean line.

The Technique

Ask for a drywall blade for your reciprocating saw — multiple manufacturers make them, and the reaction of everyone who first meets one (including the contractor in the source video, and at least one hardware store employee who didn't know it was on his own shelf) is the same: how did I not know about this?

What makes it different:

• Short and stiff — the blade is sized to get through the drywall and not much further, so a plunge cut can't wander deep into the cavity toward wires and pipes the way a 6-inch wood blade does.
• Gypsum-specific teeth — coarse and fast in drywall, leaving a cleaner edge with less shredded face paper and less dust-cloud chewing than a wood or demo blade.
• Made to plunge — start holes for outlet cutouts, access openings, and demo cuts happen right off the tip, no drilled starter hole.

For opening up walls — leak hunting, outlet moves, demo day — it turns the recip saw you already own into the right tool instead of a risky one.
