pbj:
I have some broken piece of jigsaw blade that I secured to a screwdriver shaft. Something really high tech like electrical tape or similar to hold it all together. Anyway, I can hold the apparatus like it’s a pencil and it absolutely tears through pumpkins for Halloween. Since you’re working with such thin wood I wonder if something similar wouldn’t work. Maybe just wrapping most of the blade with tape and doing it by hand? Oddly, last month I went through a box of tools I pulled out of a dumpster many years ago and found myself in possession of dozens of fret saw blades.

Zebidee:
Was thinking similar myself. Not so much about dumpster diving, but that a somewhat wider blade would help with control and minimise the twisting. Something like a hacksaw blade, centimetre wide or so, you'd need the teeth to be close together to ensure control.

That wouldn't work. These blades are about .3 mm thick and flexy as heck. You need something that pulls them at both ends to keep them rigid. If they are not rigid enough, you can turn the saw to a 50-70 degree angle and the blade still doesn't turn. I had to buy a saw with a different locking mechanism to even be able to use those blades.
What absolutely baffles me is that I get this problem now, after using this type of blades for about half a year without any issues.

Doctor: Nurse! Scalpel!
Nurse: How about a hacksaw?

1 mm is considered to be very wide, 1 cm would be like trying to use a jigsaw to do fine cuts. Doing a really tight radius would be impossible, nevermind trying to do a 90 degree angle.

Have you ever considered trying a diamond wire saw? .6mm kerf and it doesn't care which direction you go. The only drawback might be loading, but I have found the remains of a dried up tube of silicone caulk (waste not, want not :) ) works very well for cleaning wood out of sander belts, etc. so it should work for this as well.

Seriously though, a hacksaw would be a better choice than scalpel if you were performing an amputation. Dr Zeb would probably want both, for different parts of the job.

The suggestion was purely for those funky straight bits you mentioned, not the fine cuts.

But I get that you might make another choice, maybe something in between, a bit less like a hacksaw and more like a fretsaw?
