Has anybody found a close cousin to the Bosch OSC118F oscillating tool blade, (now discontinued)? That's the one Justin Fink rated the best in his Torture Test article in 2012. It was particularly useful for freeing stuck windows because the metal was so thin (.022" by my caliper). Bosch tech support tells me their OSL114F will work, but that pig is .125" thick. Might as well use a chainsaw.
Anybody out there know of something better?
