Multitool blade to cut plaster over plasterboard?

[cdbe]

You’re kidding

Not in the slightest.

Not in the slightest.

A jigsaw will certainly cut any pipe and cables I have in there

If you have a angle grinder use a 1mm disc to cut some more teeth when original wear down.

what does a new blade cost?

and what do you value your time at, per hour?

I don't think I would have the guts to use circular saw above my head, particularly not when then is a risk of hitting screws or mails.

Let's just say is can be "interesting", but perfectly doable with the modern generation of lightweight cordless saws - not so sure I'd try it with a corded saw though. The biggest problem is dealing with all the crud you get pelted in the face with - makes hard hat, goggles and FFP3 mask a necessity. A sharpish blade will just slice through even hardened drywall screws with just a bit of sparking, but the PB does blunt blades quite quickly.

A mulitool makes for a far less "buttock clenching" experience - but the blades don't last long, so cheapies are the best to use IMHO
