Warning: Stop quenching 1084 in motor oil, my first blade finally survived a bend test
I kept reading guys on here saying motor oil is fine for 1084, so that's what I used for my first 6 knives, and every one of them came out of the quench with a warped edge or a crack. Last week I switched to warm canola oil heated to about 130 degrees and my 8 inch chopper passed a 90 degree bend test without snapping, which felt like a small win after a year of ruining steel. Am I the only one who thinks the motor oil advice floating around is just leftover from guys quenching leaf springs, or does it actually work for someone out there?

130 degrees on the canola, how'd you dial that in?
