I thought those cheap lens spanner wrenches from eBay were junk

I bought a set for $22 last year and the first one snapped trying to get a stuck filter ring off a Canon FD 50mm. But my coworker in Dallas showed me his trick of heating the metal with a lighter first to soften the factory threadlock, and the second wrench in the set worked perfectly. Has anyone else found a weird fix that made a tool you hated actually useful?

I used to agree but that heat trick actually saved my vintage lens.

Maybe the trick works because old lens glue was different.

Honestly, I've had the exact opposite experience. I bought a similar set and they just bent on the first tough filter. Heating the metal seems like a good way to wreck the lens coating or melt a seal. Sometimes a tool is just poorly made, and no hack fixes bad materials. I'd rather spend a bit more on a single solid wrench than fight with junk.
