I’ve received razors with a similar amount of warp. By rolling the razor on the stone, you can generally get to the edge everywhere. You have to be diligent about it, though. If you use your vice, apply pressure very slowly and let the deformation you apply to the razor set in the vice for a few minutes before you remove pressure. I doubt that it would hurt to heat the blade up a bit but this is @djundjila’s domain more than mine.

As to heating up, what temps are we talking about as to not interfere with the tempering?
gcgallant@sub.wetshaving.social 2 hours ago
I honestly don’t know if it will make a difference. I would take a butane lighter and slowly heat the entire blade to the point where touching the edge with fingers is uncomfortable. This should be way below the temperature it would take to alter the temper.

Tempering is usually done at around 500°C, so you’d definitely want to stay far away from those temps.

I have consumer-grade kitchen ustensils, and I doubt that even with fat, I will get much above 300 degrees (assuming I don’t set fire)

A regular kitchen gas stove is about 2000°C, and a crème brûlée torch even more, so yes, avoiding fire might be a good idea :)
